If you’d like to discontinue consuming Marijuana, then you may simply quit "cold turkey". There is no physiological dependence nor a risk for withdrawal in regards to Cannabis Sativa and it’s consumption. However, you may use patches of lessening concentrations until you are completely abstained from consuming cannabis if you find it aids you.
The criteria for marijuana abuse are outlined by the Substance Abuse and Mental Health Services Administration as the following: "disruptions in functioning at work, school or home; persistent, unsuccessful attempts to cut down on use; and the development of withdrawal symptoms, such as restlessness, insomnia, nervousness, anger, or depression upon cessation of use."
