yay he joined!! now that you are in the chat! why is krokodil so cheap? i heard its 6 dollars per injection?!

Hi There 0500651!
It's cheap probably because it's a horrible drug! As you might know, it rots flesh and causes horrible pain.
Bottom line: stay away from it!

Yeah my mom sometimes smokes Esigs

-Sazabi12, Illinois

Hi Sazabi12 -- Thanks for sending me this question.  Ecigs are growing in popularity, but we are just beginning to learn about their effects, so we don't have a lot of scientific data yet.  While they may have promise to help adult smokers quit smoking regular cigarettes, but again, more research needs to be done. There have been studies on what's in e-cigs, and they found they have varying amounts of nicotine in them, the vapor may also contain some known cancer causing agents, metals, etc.  The bottom line seems to be that you don't know what you are getting in these products. You're a great kid and I can tell you really love your Mom and want her to be healthy.  Here is some information that you can read with her -- http://www.drugabuse.gov/publications/drugfacts/electronic-cigarettes-e-cigarettes and http://teens.drugabuse.gov/drug-facts/tobacco-nicotine-e-cigarettes

You said "there's no evidence marijuana really has medicinal effects." What do you think about this: http://www.cancer.org/treatment/treatmentsandsideeffects/complementaryan...

-AlpacaLlama, Maryland

Not me...Marijuana may help with nausea, e.g., related to cancer chemotherapy treatment, and it increases appetite in people with severe weight loss, and it may also help with pain. But, we are hopeful that there will be better medications (that don't have to be smoked) that use the ingredients in marijuana that can be therapeutic, without some of the unwanted side effects (memory problems).

You say marijuana is addictive but 9% is really small!

-EmmMaranvi, Maryland

True--9% sounds small--but since so many people use it, that translates into more than 4M people in this country alone. Its true for all drugs that most of the people who use them don't become addicted, but its still a risk--for some more than others.  (and of course there are other risks that have nothing to do with addiction--like car wrecks if you drive high or combine with alcohol).
