what symptoms would a heavy user have if trying to kick the habit?

using cocaine - seriously bad. Full Stop.

l am thinking yes because it also gives you a risk for lung cancer

do not know but l have been sneezing and my nose has not stopped running all day after a mad weekend

Put it this way l have a friend who got into smoking coke he is only 25 smoking it a few years took a really sore throat went to the doctors got referred to the hospital and has now got throat cancer he is going threw chemo at the moment but because it is so addictive he still smokes it all l can say its very addictive and what it does to your body is it really worth it?

Smoking cocaine is a waste of the drug; only amateurs try smoking coke in powder form. Nobody wants to admit to smoking crack because crackheads r the bottom feeders in the drug world. Just for starters, only 3% of crack addicts get clean & stay clean. Crack is more addictive than snorting or even slamming because it only takes seconds to get to the brain & produces a feeling of a whole body orgasm.

If he was trying to get clean, symptoms would be checking himself into long-term (at least a year) rehab, going daily to 12 step meetings, getting a sponsor & doing what the sponsor tells him to do, changing all playplaces, playthings, & playmates (calling his dealer telling him to never contact him, removing himself from all situations where he may run into his using friends), he would also be seeing an addiction specialist, counselor, seeking therapy, & doing service work. These would be signs of someone trying to get clean.

If the question is what r the signs of someone who is not using at the moment. Grinding jaw, very irritable, sleeping many hours, eating lots of food, crack-cough (hacking cough that produces black phlegm), nasty, argumentative, muscle jerks, twitching foot, head tilt.
