You don't want to give it up. So, in your head, why should you give it up?
Symptoms of Marijuana Addiction:
Marijuana tolerance:
Either need for markedly increased amounts of marijuana to achieve intoxication, or markedly diminished effect with continued use of the same amount of marijuana.
Greater use of marijuana than intended:
Marijuana taken in larger amounts or over a longer period than was intended.
Unsuccessful efforts to cut down or control marijuana use.
A great deal of time spent in using marijuana
Marijuana use causing a reduction in social, occupational or recreational activities.
Continued marijuana use despite knowing it will cause significant problems.
Is this you?
You can stop but you will need professional help. It is true that some can just quit and be done with it, but many cannot do that. If you are truly desiring to quit smoking pot, then I do hope you receive help.
