I need to know how long do they stay in my system? Week or days??

I no in your urine its only detectable for 1 to 2 day but I myself am trying to find out how long it is decteable in the blood hope this helps o drink lots of water 2

Drinking a lot of water to flush out your system is very bad do not do it! I don't know how long it takes to get it out of your blood but if you Google drinking water to flush out your system it says that you can die... be careful
