Is Weed Legal in Bonn? German Cannabis Laws, Limits and Practical Advice

Yes, cannabis is partly legal for adults in Bonn, but it is not legal in the same way as alcohol or tobacco. Bonn follows Germany’s nationwide cannabis rules. Since 1 April 2024, adults may possess limited quantities of cannabis, grow a small number of plants at home and, subject to strict conditions, obtain cannabis through non-commercial cultivation associations.

That does not mean that cannabis is freely sold in Bonn. Licensed recreational cannabis shops do not currently operate under Germany’s adult-use system, and buying cannabis from an unauthorised dealer remains illegal. Public consumption is also restricted in many places, and driving after using cannabis can lead to serious legal and safety consequences.

This guide explains what residents and visitors need to know about cannabis in Bonn. The rules can change, so anyone facing a police investigation, driving issue or other legal problem should obtain advice from a qualified German lawyer or check current information from official authorities.

Is weed legal in Bonn?

For adults aged 18 and over, cannabis is legal in Bonn within defined limits. The relevant law is Germany’s Cannabis Act, commonly known as the CanG. It applies in Bonn just as it applies in Cologne, Berlin, Munich and other German cities.

The law allows limited possession for personal use and permits adults to cultivate cannabis at home under specific conditions. It does not create a general retail market. In practical terms, the position is:

• Adults may possess up to 25 grams of cannabis in public.
• Adults may keep up to 50 grams of dried cannabis at their residence or usual place of residence.
• Adults may grow up to three cannabis plants for personal use.
• Adults may access cannabis through approved non-commercial cultivation associations if they meet the membership and residence requirements.
• Unauthorised selling, purchasing, importing and exporting remain offences.
• Consumption is prohibited in several locations and situations.

These limits are not a licence to carry unlimited cannabis in separate bags or to supply friends. The rules concern an individual’s total permitted possession and are designed for personal use.

Who can legally possess cannabis in Bonn?

The adult possession rules apply to people aged 18 or older. Minors cannot legally possess cannabis for recreational use. If a person under 18 is found with cannabis, authorities may involve parents or guardians and youth welfare services, and the cannabis may be confiscated. Supplying cannabis to a minor is particularly serious.

Adults should also be able to keep cannabis secure from children and other unauthorised people. Home-grown cannabis must be protected against access by minors. Leaving plants or harvested cannabis where children can easily reach them can create legal problems even if the quantity is within the permitted limit.

Public and private possession limits

The main limits are easy to confuse. An adult may carry up to 25 grams in public, such as while walking through Bonn or travelling on public transport. At home, the permitted maximum is 50 grams of dried cannabis. The law also permits up to three live cannabis plants per adult at a residence or usual place of residence.

The home limit does not automatically mean that a person may carry 50 grams outside. A person who takes more than 25 grams into public may face a violation or criminal consequences depending on the quantity and circumstances. Cannabis should be stored safely and separately from situations where it could be mistaken for an attempt to supply others.

Can you buy weed legally in Bonn?

There is no general recreational cannabis shop system in Bonn. Unlike some jurisdictions that operate licensed dispensaries, Germany’s current framework does not allow ordinary commercial retailers to sell recreational cannabis to walk-in customers. A shop advertising cannabis for recreational use should therefore be treated with caution.

Buying cannabis from an unauthorised seller remains illegal, even if the buyer is an adult and the amount is small. Possession of a permitted amount does not make the purchase method lawful. Street purchases also carry risks involving unknown strength, contamination, scams and police investigations.

Cannabis cultivation associations

Germany permits non-commercial cultivation associations, often called cannabis clubs. These organisations are subject to licensing, cultivation, record-keeping and youth-protection requirements. They are not conventional cafés, dispensaries or tourist shops, and they cannot simply sell cannabis over the counter to anyone who walks in.

Membership conditions generally include being at least 18, having Germany as a place of residence or habitual abode for the required period and joining for a minimum membership period. Associations may impose additional rules, fees and waiting lists. Members must collect cannabis according to the statutory limits, and on-site consumption is not a normal feature of the system.

Visitors who are in Bonn for a short holiday should not assume that a cannabis club can legally serve them. Residence and membership requirements are important, and clubs must verify eligibility. Anyone considering joining should check that the organisation is properly authorised and that its current procedures comply with the latest law.

Where is cannabis consumption prohibited in Bonn?

Even when possession is lawful, smoking or otherwise consuming cannabis may be illegal at the location where it takes place. Bonn has many busy pedestrian areas, parks, schools and family facilities, so location matters.

Consumption is prohibited in the immediate presence of people under 18. In addition, the law restricts consumption in or near certain protected places, including:

• Schools and children’s and youth facilities.
• Playgrounds.
• Publicly accessible sports facilities.
• Cannabis cultivation associations and their immediate area.
• Pedestrian zones between 7:00 and 20:00.

The law also creates distance restrictions around the entrances of several protected facilities. Because measuring the relevant distance in a real location can be difficult, it is safer not to consume near schools, playgrounds, youth centres or sports grounds at all. A park is not automatically a cannabis-free area, but it can contain a playground, sports facility, school route or children nearby, making public use legally risky.

What does “immediate presence of minors” mean?

Adults must not consume cannabis when minors are directly present. This is stricter than simply avoiding handing cannabis to a child. For example, smoking in a group that includes someone under 18 can create a problem, even if the cannabis belongs only to an adult. Responsible users should move well away from children and avoid exposing them to smoke or vapour.

Pedestrian zones and public transport

Consumption in pedestrian zones is restricted from 7:00 to 20:00. Bonn’s central shopping streets and other traffic-calmed areas may fall within this category. Public transport stations and vehicles can also have operator rules prohibiting smoking or vaping, and other public-order rules may apply.

Do not assume that a quiet street, railway platform or bus stop is a safe place to consume. Even where the cannabis-specific restrictions do not apply, smoking may breach house rules, transport conditions or local public-order requirements.

Can you smoke weed in Bonn parks or on the street?

There is no simple rule that cannabis is legal everywhere outdoors. Outdoor consumption depends on the time, the exact location, nearby protected facilities and whether minors are immediately present. A secluded area away from children and protected facilities may be less problematic, but users remain responsible for identifying the restrictions.

In particular, do not consume near playgrounds, schools, youth centres or sports facilities. Do not consume in a pedestrian zone during the restricted daytime hours. Be considerate about smoke drifting towards other people, entrances, residential buildings and family areas. Police may still intervene where there is a suspected offence, disturbance or concern about youth protection.

Is home growing legal in Bonn?

Adults may grow up to three cannabis plants for personal use at their residence or usual place of residence. The plants and harvested cannabis must be protected from access by children and other unauthorised people. Home growing is not permission to sell, give away cannabis commercially or turn a flat into an unlicensed production site.

Tenants should also consider separate housing issues. The cannabis law does not override a rental agreement, building rules, fire-safety requirements or nuisance law. Strong odours, unsafe electrical equipment, water damage or mould can cause disputes with landlords and neighbours. Growing plants in a shared garden or communal area may also raise ownership and access problems.

Home cultivation must not be used to supply people outside the permitted personal-use framework. Sharing cannabis can be legally complicated, particularly where money, repeated transfers, minors or quantities suggesting supply are involved.

Can tourists bring cannabis to Bonn?

Visitors should not bring cannabis into Germany from another country. Importing and exporting cannabis remain prohibited, including carrying it across an international border by car, train, plane or post. This applies even if cannabis was legally purchased in the country of departure or if the destination is Bonn.

Germany’s domestic possession rules do not create a travel exemption. A visitor may still face border controls, confiscation, fines or criminal proceedings for importing cannabis. The same warning applies when leaving Germany: do not take cannabis from Bonn to another country.

Tourists should also be cautious about carrying cannabis on domestic journeys. Although adults may possess up to 25 grams in public, carrying it into airports, secure facilities or other restricted premises can create additional issues. Never assume that possession rules guarantee permission to enter a particular venue with cannabis.

Cannabis and driving in Bonn

Driving after cannabis use is one of the most important legal risks. Cannabis can impair reaction time, attention and judgement, and impairment may last longer than expected. A person who feels sober may still be unsafe or legally exposed.

Germany introduced a statutory THC blood-serum limit of 3.5 nanograms per millilitre for ordinary driving offences in 2024. This is not a guaranteed safe amount and does not authorise driving while impaired. Driving with signs of impairment can lead to more serious consequences regardless of the measured THC level. A combination of cannabis and alcohol is treated especially strictly.

Separate zero-tolerance or stricter rules can apply to novice drivers during the probationary period and drivers under 21. Professional drivers may also face workplace and licensing consequences. Police can order testing after a traffic stop or collision, and a driving authority may assess fitness to drive independently of a criminal or administrative case.

• Never drive after consuming cannabis or while uncertain about its effects.
• Do not combine cannabis with alcohol.
• Use public transport, a taxi or a sober driver instead.
• Do not cycle or use an e-scooter while impaired.

What about CBD and medical cannabis?

CBD products are not automatically the same as legal recreational cannabis. Their legality depends on the product, THC content, intended use, labelling and applicable food, medicine or consumer-product rules. Some products sold online or in shops may contain more THC than expected or may not comply with German requirements.

Medical cannabis is regulated separately. Patients generally need a prescription and must obtain medicinal products through lawful medical and pharmacy channels. A prescription does not automatically permit recreational possession, sharing or driving while impaired. Patients should follow medical advice and ask a doctor or pharmacist about driving and treatment-related responsibilities.

What penalties can apply?

Consequences depend on the amount, the conduct and the surrounding facts. Exceeding the permitted limits, supplying cannabis, involving minors, importing cannabis or consuming in a prohibited place can lead to confiscation, an administrative fine or criminal proceedings. Repeat offences and conduct suggesting commercial dealing are treated more seriously.

Police may seize cannabis while investigating. A driving incident can affect a person’s licence, insurance and employment as well as creating a fine or criminal case. Foreign nationals may also need to consider immigration consequences. If authorities contact you about possession, supply or driving, do not ignore the correspondence; prompt legal advice can be important.

How Bonn compares with other German cities

The core cannabis rules in Bonn are federal, not city-specific. Cologne, which is nearby, follows the same nationwide possession, cultivation and consumption framework. Differences may arise in enforcement priorities, the availability of cultivation associations, local venue policies and the practical layout of protected areas.

Our guide to whether weed is legal in Cologne provides a useful comparison for people travelling between the two cities. It is still important to check the exact location and current rules rather than relying on assumptions based on another city.

Practical checklist for adults in Bonn

• Carry no more than 25 grams in public.
• Keep no more than 50 grams of dried cannabis at home.
• Do not grow more than three plants per adult.
• Secure plants and cannabis away from children and unauthorised people.
• Do not buy from street dealers or unlicensed sellers.
• Avoid consumption near schools, playgrounds, youth facilities and sports facilities.
• Do not consume in pedestrian zones between 7:00 and 20:00.
• Never import or export cannabis across a national border.
• Do not drive, cycle or use an e-scooter while impaired.
• Check current official guidance if your situation involves a club, prescription, police contact or driving licence.

Conclusion: cannabis is partly legal, not freely available

So, is weed legal in Bonn? For adults, limited possession, home cultivation and regulated association access are legal under Germany’s current cannabis framework. However, Bonn has no general recreational retail market, and buying, selling, importing or exporting cannabis remains unlawful outside the permitted system.

The safest approach is to stay within the quantity limits, keep cannabis away from minors, avoid protected public locations and never drive after using it. Because German cannabis and driving rules may develop further, residents and visitors should check current official information before relying on any legal summary.
