I know from personal experience that marijuana addiction is very real. I smoke marijuana every day, and I feel serious withdrawal when I have to go without for more than a day. I smoked cigarettes for ten years before I quit, so I know what addiction and withdrawal are all about.

Symptoms of THC withdrawal include nausea, headache, insomnia, confusion, extreme irritability, and an inability to feel good without the drug. These symptoms can last up to a week. I think that because it's relatively easy to quit smoking pot compared to cigs or hard drugs, people say marijuana isn't addictive.
