yes you can,
It depends on what drug you did.
30 days
Yes it will test positive for about one week
Only if the method of drug testing returns results within a week. In actuality, testing urine for certain drugs requires only a few minutes; it is the backlog in a lab which takes time. If you are worried about someone else finding out about drugs in your system, that is a risk you take. You might get one of those home drug test kits and test yourself.
a week
It depends what kind of test is performed. Typically, drugs are tested for by a urine test, in which case magic mushroom use would not show up (the detection period is typically up to 4 days). Additionally, it is uncommon to test for magic mushrooms anyway.
Will be trying this next week...will post then
A urine test will show if you have marijuana or alcohol in your system. It will also pick up Benzodiazepines such as Valium, Xanax, or Ativan. It also shows if you have narcotics in your system such as Percocet, Lortab, Codeine, Morphine, or other opiates. Meth or Crystal Meth can both be picked up as well as PCP, LSD, Ecstasy, and Heroin. A urine test can still be positive even if it's been more than 72 hours since you have had these drugs, some them will still test positive more than a week later. Marijuna and cocaine are two drugs that show up in drug tests. Many employers use this to screen new employees.
Benzodiazepines can be detected up to a week after use.
If PCP is used in a typical dose on a single occasion, it is likely to be undetectable by a standard urine test after a week. Of course, this can vary based on the individual, especially if liver or kidney function is impaired. If PCP is used regularly, it can usually be detected in a urine test for about a month.
Coke leaves the body in 72 hours.
Yes, it will stay in your system for a week or two
