1. to my knowledge most drugs leave your system within 24hours, although canabis can be detected up to 3 weeks
2. It all depends on the drug - Alcohol (Beer, Booze, Hooch, Liquor, Wine), 1hour to perhaps 10 or 12 hours (Yes, alcohol IS a drug! Drinking more than "in moderation" can lead to alcohol (drug) abuse...and perhaps alcoholism. Amphetamines (Biphetamine, Black Beauties, Crosses, Dexedrine, Hearts), 1-2 days Anabolic steroids (Stanzolol, Stanazolol, Nandrolene; Steroids, Roids, Juice), oral- up to 3 weeks; injected- up to 3-6 months and more Barbituates (Amytal, Nembutal, Seconal, Phenobarbital; Barbs), 2-3 days Benzodiazepines (e.g., Ativan, Halcion, Librium, Rohypnol, Valium; Roofies, Tranks, Xanax), 2-3 days Cocaine (Candy, Coke, Crack, Flake, Rocks, Snow, Whitecoat), (Candy, Coke, Crack, Flake, Rocks, Snow, Whitecoat), 1-2 days Codeine (e.g., Fiorinal w/codeine, Robitussin A-C, Empirin w/codeine, Tylenol w/codeine, 1-2 days GHB (G, Grievous Bodily Harm, Goob, Liquid Ecstasy, Liquid X), 1-2 days Heroin (Horse, Smack), 1-2 days Inhalents, just a few hours Ketamine (K, Kit Kat, Special K, Vitamin K), 2-4 days LSD (Acid, Blotter, Microdot, Yellow sunshine), a few hours or up to 5 days Marijuana (Bud, Blunt, Grass, Herb, Pot, Reefer, Sinsemilla, Smoke, Weed), 2-5 days (the daily, heavy user can sometimes be detected up to 30+ days) MDMA (Ecstasy), 1-5 days Methadone, 1-7 days Methamphetamines (Crank, Crystal, Desoxyn, Glass, Ice, Speed), 2-4 days Methaqualone (Ludes, Quaaludes), 10-15 days Nicotine (Cigarettes, Cigars, Habitrol patch, Nicorette gum, Nicotrol spray, Prostep patch; Smokeless tobacco, Snuff, Spit tobacco), 1-2 days Opiates (i.e., Opium: China, Dreams, Laudanum, Paregoric; Dover's Powder), 1-2 days Oxycodone (OxyContin, Percolone, Roxicodone), 1-2 days PCP (Angel Dust, Boat, Hog, Love Boat), 1-8 days For chronic drug users, drugs (other than alcohol) can be retained in the system much longer by the chronic-user after their last use. For instance, marijuana and PCP can be detected for up to 60-90 days after lengthy, heavy-use periods of use. Hope that helps.
