YES YES YES, do not handle it for no reason if you have a you/A coming up in the next 2-3 days! If you can put it on your tongue or gums to receive a numbing effect then it can definately enter your bloodstream! I would say if you touch it then it will probably only stay in blood or urine for 24-36hrs depending on how much you handle!! Don't do it!
Yes it can. This happened to 2 friends of mine. They had a positive drug test for cocaine due to handeling it. It gets in the system through the pores.
Bull yes it can
Yes it can enter. So it looks like my aunts getting out
No Crack Cocaine can not get into your system through your pores, but you shouldn't be handling it anyways, it is VERY harmful to you, and those around you. Drugs shouldn't have ever been introduced into the world in the first place, but since they were (mostly as experimental medicine use) they should only be handled by the authority.
