According to the DSM-5, (Diagnostic and Statistical Manual of Mental Disorders, fifth edition) the criteria for Cannabis Use Disorder is as follows:

Use of cannabis for at least a one year period, with the presence of at least two of the following symptoms, accompanied by significant impairment of functioning and distress:

Difficulty containing use of cannabis- the drug is used in larger amounts and over a longer period than intended.

Repeated failed efforts to discontinue or reduce the amount of cannabis that is used

An inordinate amount of time is occupied acquiring, using, or recovering from the effects of cannabis.

Cravings or desires to use cannabis. This can include intrusive thoughts and images, and dreams about cannabis, or olfactory perceptions of the smell of cannabis, due to preoccupation with cannabis.

Continued use of cannabis despite adverse consequences from its use, such as criminal charges, ultimatums of abandonment from spouse/partner/friends, and poor productivity.

Other important activities in life, such as work, school, hygiene, and responsibility to family and friends are superseded by the desire to use cannabis.

Cannabis is used in contexts that are potentially dangerous, such as operating a motor vehicle.

Use of cannabis continues despite awareness of physical or psychological problems attributed to use- e.g., anergia, amotivation, chronic cough.

Tolerance to Cannabis, as defined by progressively larger amounts of cannabis are needed to obtain the psychoactive effect experienced when use first commenced, or, noticeably reduced effect of use of the same amount of cannabis

Withdrawal, defined as the typical withdrawal syndrome associate with cannabis, or cannabis or a similar substance is used to prevent withdrawal symptoms.

This is similar to substance misuse disorder.

The DSM 5 recognizes substance-related disorders resulting from the use of 10 separate classes of drugs: alcohol; caffeine; cannabis; hallucinogens (phencyclidine or similarly acting arylcyclohexylamines, and other hallucinogens, such as LSD); inhalants; opioids; sedatives, hypnotics, or anxiolytics; stimulants (including amphetamine-type substances, cocaine, and other stimulants); tobacco; and other or unknown substances. Therefore, while some major groupings of psychoactive substances are specifically identified, the use of other or unknown substances can also form the basis of a substance-related or addictive disorder.

Substance use disorders span a wide variety of problems arising from substance use, and cover 11 different criteria:

Taking the substance in larger amounts or for longer than you're meant to.

Wanting to cut down or stop using the substance but not managing to.

Spending a lot of time getting, using, or recovering from use of the substance.

Cravings and urges to use the substance.

Not managing to do what you should at work, home, or school because of substance use.

Continuing to use, even when it causes problems in relationships.

Giving up important social, occupational, or recreational activities because of substance use.

Using substances again and again, even when it puts you in danger.

Continuing to use, even when you know you have a physical or psychological problem that could have been caused or made worse by the substance.

Needing more of the substance to get the effect you want (tolerance).

Development of withdrawal symptoms, which can be relieved by taking more of the substance.
