Cannabis

Cannabis is the plant used to make marijuana, hash and a range of extracts. THC produces the intoxicating effects; CBD does not produce the same high. People smoke or vape it, or consume it in food and drinks. Reasons include relaxing, socialising, changing the experience of music, or trying to manage pain, appetite or sleep problems.

Self-treating symptoms is different from receiving medical care. Products vary, and their THC content may be unclear. Use can also take up more room in your life than intended: planning evenings around getting high or avoiding places where you cannot use it matters, even if you still meet your work commitments.

Possible effects include relaxation, laughter, hunger, sleepiness and an altered sense of time. Dry mouth and difficulties following a conversation or remembering what you just said can accompany them. Edibles take longer to have an effect and may keep you intoxicated longer than expected.

The experience can turn into panic, a racing heart, paranoia or feeling out of control. Consuming more before an edible takes effect can lead to poisoning. Severe confusion, hallucinations or unresponsiveness need urgent medical attention. Do not drive on the assumption that feeling less high means you are unimpaired.

Dependence can develop. Stopping frequent use may bring insomnia, irritability, anxiety and appetite loss; using again to relieve withdrawal can make quitting difficult. Smoking harms the lungs. Cannabis use is associated with increased psychosis risk, particularly with early or frequent use. Avoid it during pregnancy and breastfeeding.

Alcohol and sedatives can compound impairment, and cannabis can interact with medicines. Disclose use when reviewing a prescription, and keep edibles away from children. In Spain, illicit possession or use in public places can lead to fines, and trafficking is a criminal offence. Membership of a cannabis club does not give blanket permission to carry or use cannabis elsewhere.
