- Cannabis & You
The use of cannabis typically causes a sedative effect, making the drug less likely to cause violence in users than other substances such as alcohol and stimulants (e.g. amphetamines and cocaine).
However, sometimes when people use cannabis it can cause fear, anxiety, panic or paranoia, resulting in an aggressive outburst. For most people, however, once the effects of the drug wear off, their behaviour gradually improves.
Studies show that violence can occur more often among people who use cannabis regularly, rather than those who use it occasionally or not at all. It is a matter for current research as to why this is the case. It may be because people with violent tendencies can also have a range of other psychosocial problems and are therefore more likely to use cannabis. It is also important to remember that cannabis is part of the illegal drug market, increasing the chance of violence to occur in some social interactions.
Research also shows that cannabis users who commit aggressive acts usually have a history of violence before they start using the drug.

Experiencing any of these symptoms can make a person angry, which is an emotional response to feeling threatened or frustrated. Anger ranges from mild irritation to violent rage. Some people can express their anger in a controlled and constructive way while others lash out in an aggressive, uncontrolled way, either immediately or letting their feelings build up. This can lead to intimidating, violent or bullying behaviour, endangering them, other people and property.
The impact and the effects of violence on an individual can be profound and long-lasting, so doing all you can to prevent violence actually occurring is important.
The aim of calming someone down is not to prove them right or wrong, but to allow them to regain control of their behaviour without resorting to violence.
The best time to intervene is when a person is feeling anxious. Be supportive, empathic and stay neutral. Ask them what is wrong and try to calm them down. Move them to a quiet place and stay with them until the effects of cannabis wear off.
If a person's behaviour becomes aggressive, you could try the following tips to help calm them down:
After the effects of cannabis or cannabis withdrawal wear off, talk to them about what happened, how it affected you and those around you, and how this could be prevented in future.
You can do things that may reduce the likelihood of this happening to them again. These may include the following:
