With regular use, people can develop a mild tolerance to cannabis. This means they need to take more and more to get the same effect.
Heavy and frequent use of cannabis can cause physical dependence. Physical dependence occurs when a person’s body has adapted to a drug and is used to functioning with the drug present.
It is possible to become psychologically dependent on cannabis. This means that using cannabis becomes far more important than other activities in their life. Some people crave the drug and find it very difficult to stop using it.
