Cannabis is a plant with hundreds of active compounds. The dried flowers are commonly sold as flower, weed, or buds. Hash is a concentrated product made from the plant’s resin glands using techniques such as dry-sifting, static separation, and ice-water extraction. Both are consumed recreationally and medicinally.

What are the effects of cannabis?

Cannabis affects everyone differently. Effects often include relaxation, mild euphoria, short-term memory disruption, heightened senses, increased appetite, and a slowed sense of time. The experience depends on the strain, dose, tolerance, setting, and state of mind.

Sativa, indica, or hybrid?

Most modern strains are hybrids. The traditional split is more useful for marketing and broad categorisation than for predicting a specific effect. Ask our budtenders for strain-specific information and consider the cannabinoid and terpene profile rather than the label alone.

THC, or tetrahydrocannabinol, is the main psychoactive compound in cannabis. It produces the effects commonly associated with cannabis and is also used medically for pain, nausea, and appetite stimulation. Higher THC levels mean stronger effects and a greater chance of side effects, especially for new or sensitive users.

CBD, or cannabidiol, does not produce a high. Its effects and potential benefits are still being studied. CBD can interact with regular medication, so speak to your doctor before consuming it alongside other medication.

What are cannabinoids?

Cannabinoids are active compounds that interact with the body’s endocannabinoid system. THC and CBD are the best known, while compounds such as CBG and CBN are gaining attention as research expands. Cannabis contains more than 100 known cannabinoids, mostly in trace amounts.

Terpenes are aromatic compounds that give cannabis its smell and taste, such as citrus, pine, pepper, earth, or fuel. Research is still developing, but terpenes may influence effects in various ways. They are also found in other plants, fruits, and vegetables.

Flavonoids are plant compounds that contribute to cannabis’s colour, flavour, and potential antioxidant properties. They are less studied than cannabinoids and terpenes, but are increasingly recognised as part of what gives each strain its distinctive character.

What does potency mean?

Potency usually refers to the THC percentage. Higher THC does not automatically mean better. For new users, lower potency is the safer starting point.

What is a sensible dose of THC or cannabis?

There is no universal dose. Sensitivity varies widely and every strain or product can affect people differently. Start low, go slow, and wait. Inhaled effects appear within minutes and peak after around 30 minutes. Edibles can take 30 to 120 minutes to appear and last much longer.

What are the potential negative effects?

Cannabis can cause dry mouth, red eyes, short-term memory disruption, and impaired coordination. Higher doses or low tolerance can cause anxiety, paranoia, or a racing heart. These effects usually pass as the cannabis wears off.

How do mindset and setting affect the experience?

Your mood, expectations, and mental state have a major influence on your experience. The environment matters too. A relaxed, familiar setting with people you trust reduces the chance of an uncomfortable experience.

What if I feel too high?

Stay calm, move to a quiet and familiar place, drink water, avoid taking more substances, and ask someone you trust to stay with you. Seek medical help if symptoms feel severe or do not improve.

How long do effects last?

Inhaled cannabis typically lasts 2 to 4 hours. Edibles can last 4 to 8 hours, sometimes longer. Effects on coordination and memory can persist long after the obvious high fades.

Smoking, vaporising, or edibles?

Smoking is common but carries health risks from combustion. Vaporising heats the plant without burning it, reducing harmful byproducts. Edibles avoid inhalation but are harder to dose: effects are slower, stronger, and longer-lasting. Choose a method that fits your experience and health situation.

Can I mix cannabis with alcohol or other drugs?

Combining cannabis with alcohol or other substances is not recommended. Substances can intensify each other and increase the risk of unpleasant or unpredictable reactions.

Can I use cannabis with medication?

Cannabis can interact with prescription and over-the-counter medication, including blood-pressure medicines, sedatives, antidepressants, and blood thinners. Always consult your doctor or pharmacist before combining them.

What are the risks of cannabis consumption?

Frequent or heavy use, especially when started young, is linked to dependency and may affect mental health and cognitive development. Heavy use can be associated with a higher risk of psychotic episodes in vulnerable people.

Is cannabis addictive?

Cannabis can lead to dependency, especially for people who start young or use it daily. Signs include cravings, difficulty stopping, and continued use despite negative consequences. Help is available through Jellinek and other addiction services.

What about mental health?

Cannabis can worsen anxiety, depression, or a predisposition to psychosis. If psychosis or mental health issues run in your family, or you have experienced psychosis yourself, consult a doctor before using cannabis.

Can you consume cannabis during pregnancy?

Cannabis should be avoided during pregnancy, when planning a pregnancy, and while breastfeeding. Consult your doctor for guidance.

Can young people use cannabis?

The brain continues developing into the mid-twenties. Cannabis during this period can affect memory, attention, learning, and other cognitive functions. Coffeeshops may only sell to adults aged 18 and over, but the health advice extends beyond that age.

Does cannabis have medicinal use?

Yes. Medicinal cannabis is prescribed for conditions including chronic pain, muscle spasms in multiple sclerosis, and nausea from chemotherapy. Recreational use and self-medication are not the same. Talk to a doctor before considering cannabis for a medical condition.

Is cannabis legal in the Netherlands?

Cannabis is not legal and is listed under the Opium Act. Under the tolerance policy, the sale and possession of small amounts are tolerated and not prosecuted when strict conditions are met.

Can tourists buy cannabis in coffeeshops?

Tourists can still buy cannabis in Amsterdam. Enforcement of the residents-only criterion differs by municipality, and some border cities do enforce it. Rules can change, so always check local policy.

Can I smoke cannabis in public?

In Amsterdam, public smoking is generally tolerated but prohibited in designated busy areas, school zones, and playgrounds. Avoid nuisance and check current municipal restrictions, as rules differ by municipality.

What does the tolerance policy mean?

The tolerance policy allows coffeeshops to sell small quantities under strict conditions. They must meet the AHOJG criteria: no advertising, hard drugs, nuisance, or sales to minors; no more than 5 grams per person per day; and no large on-site stock.

Can I travel with cannabis?

No. Rules differ between countries and crossing borders with cannabis can be a criminal offence. Do not take cannabis across borders or into the Netherlands.

How much can I possess?

What is the wietexperiment?

The Closed Coffeeshop Chain Experiment is a government pilot testing a regulated, legal supply chain from cultivation to sale in selected municipalities.

Where can I consume cannabis?

Many coffeeshops have designated smoking lounges. Elsewhere, cannabis can only be consumed where local rules allow or tolerate it. Public consumption may be restricted in certain areas, so check municipal guidance.

Can I grow cannabis at home?

Growing cannabis at home remains illegal. Police may choose not to prosecute possession of up to five plants for personal use, but the plants can still be seized. Larger-scale or professional cultivation can lead to serious penalties.

Can I drive after using cannabis?

No. Driving under the influence is illegal. THC affects coordination, reaction time, and judgement longer than the subjective high. Do not drive, cycle in traffic, or operate machinery while affected.

How does the police test for cannabis?

Police use a saliva test during traffic controls. A positive result leads to a blood test for confirmation. The same rules apply to medicinal cannabis; a prescription does not exempt you from the legal limit.

What are the penalties?

Penalties include fines, suspension of the driving licence, and in serious cases criminal prosecution. The exact penalty depends on the THC level and whether it is a repeat offence.

Where can I find reliable information or support?

The Trimbos Institute offers independent information on cannabis, mental health, and substance use. Jellinek provides addiction care and support. Your municipality publishes local rules, and Drugsinfo offers anonymous information and advice.

Where can I get help for cannabis use?
