Answer 1: Yes it will because you will get addicted and then you will get it into your blood streem and to your brain until your nothing.
Answer 2: Crack cocaine. like most (if not all) addictive alkaloids, can stay in your system for several weeks, and can continue to cause nervousness, loss of appetite, severe paranoia, dizzy spells, and loss of sexual ability. The length of time depends more or less on the amount smoked and the frequency of use, but can easily last six weeks or more. To avoid permanent damage, it is necessary to stop using the drug altogether. Crack cocaine is one of the most addictive substances known and competes only with heroin on that scale. The dependence, however, can be overcome without physical repercussions as it is psychlogically, but not physiologically, addicting.
