Methamphetamine is also sold in crudely cut street mixes of party drugs such as ecstasy. It stays in the system for up to eight hours.
The saliva swabs will also detect THC - the active metabolite in cannabis - which stays in the system for up to three hours after use.

So the time it stays in your system is that the same for everyone regardless of sex or weight? Because there are these variables with alcohol.
The reason I ask is... often we go out say.. to a BBQ and everyone else is drinking and I might have a cone or two, or three but I'm straightened out by the time I leave later in the day so I can drive the drunkards home.
