Gradual reduction of cannabis use

Planned gradual reduction in cannabis use is usually straightforward and can often be managed with gradual changes to daily use (eg reducing the number of bongs or joints used each day, decreasing the amount of cannabis in each bong or joint, or increasing the interval between waking and use each day). Making the changes over 1 to 4 weeks may reduce the likelihood and severity of withdrawal and the need for medications to manage symptoms, compared to stopping abruptly. Psychological interventions have a key role in assisting gradual reduction.
