Opiate addiction and military basic training?

Hey everyone. I have a friend who has been abusing narcotics on a regular basis for over a year now. His drug of choice is Dilaudid, more specifically, Hydromorphcontin. He snorts these pills on a regular basis, perhaps even daily. I don't see him that much anymore as he is usually out doing these drugs and I am currently a student at a nearby university. I fear he has become addicted to these drugs, as his physical appearance has taken an alarming decline - he has lost tons of weight, and he was a skinny fellow to begin with - now he weights maybe 110 pounds and he is about 5 foot 9, and is almost 22 years old. He claims to be going to basic training for the Army in July, but I am wondering how much of a chance he has with his addiction to opiates. He is not physically active, and usually sleeps in all afternoon. My question is directed towards people who have experience with opiate addiction and withdrawal symptoms and/or people who have went through basic training for the Canadian Armed Forces. Is it possible to quit Dilaudids cold turkey in a matter of 4 months and complete basic training subsequently? I don't believe my friend has any intentions of quitting these drugs anytime soon, and he will likely be in a state of denial if confronted about his drug abuse, saying things like "I'm just having some fun before I ship off to basic"... Furthermore, can any members of the CF tell me what the drug testing policy is for recruits. Sorry for the length of the question, and I look forward to any answers or insights that anyone can provide me with. Thank you, J.B.
