Once a person goes cold turkey and stops smoking, there are some very common marijuana withdrawal symptoms that start almost immediately and are reported by the vast majority of those who quit. The most common symptom described is a general feeling of anxiety, for all that the pot makes a person feel relaxed and unstressed the needle swings the other way when they quit. Most people tend to spend several days feeling out of sorts and generally cranky.
Marijuana is not heroin…but neither is it the same marijuana that it was 20 or even 10 years ago, and as the potency has risen almost 10 fold over the decades, so to have the risks of addiction, the risks of developing a tolerance and experiencing withdrawal symptoms with marijuana cessation.
Marijuana detox and withdrawal is not dangerous but it can be very uncomfortable, and it can be difficult to overcome the cravings back to use and abuse. Many people can use marijuana recreationally without developing dependency issues, but many hundreds of thousands cannot, and it is not at all ridiculous to seek professional assistance if you are having difficulty overcoming an addiction to marijuana.
