If you smoke canibis, for how long does it stay in your system? I.e. if you go for a urine test, how long after your last joint would they be able to detect it? What about other drugs, ecstacy for example?
According to this newspaper report http://society.guardian.co.uk/publicvoices/prisons /story/0,12261,804985,00.html
which cites a home office report in drug abuse/testing in prisons cannabis stays in the system, or is at least detectable in their tests, for 28 days whereas heroin is only detectable for upto 72 hours.
Depends how often you smoke it if you smoke it everyday all the time then it can stay in your system upto 6 months.If you have the odd joint then normally up to a month maybe less.Things suck as XTC and speed can show upto a month but thats not always the case sometimes it can only be a week again depending on how many you take.I had to have a drug test for work and i passed god knows how but i did and i had used drugs the week before.drink lots of water as flush all the toxins and that out of your body they can detect more by doing a blood test so if its only a urine test drink loads of water.
Not entirely sure how it works, but some drug testing techniques look at hair samples and this seems to provide a very good record of what someone's been taking... not sure what drugs you can detect this way though.
