Before I start, I'd just like to note that anything I write here is
for educational purpose only. Neither Google Answers nor I condone or
encourage illegal activities.

With that being said, Dextroamphetamines, a class of amphetamines take
up to 30 hours on a low dose, and up to 120 hours on a high dose. The
urine detection level is about 300ng/mL and it has half life of about
10 hours. Acidic urine enhances excretion, however artifically acidify
urine is not recommended as it can excerbate myoglobinuric renal
failure and/or rhabdomyolysis. It may also serve to concentrate the

Marijuana is a class of cannabinoids. The period of detection is
highly variable. A single use (1 joint) generally requires 24-48 hours
to test negative from urinalysis. One joint/week has detectable level
of cannabinoides 7-34 days after the last dose. A daily user may be
detectable 6-81 days after the last dose. Typical urine detection
levels are about 100ng/mL or for more sensitive instruments, 20ng/mL.
These sensitive instruments may, however, provide false positives as a
result of mere inhalation of marijuana smoke.

If you have any questions, feel free to ask for clarification before
giving a rating. I am willing to work until you are completely
satisfied with the answer to your question.

What would be considered a high dose/low dose of dextroamphetamine?

Clarification of Answer by tox-ga on 15 Jun 2004 19:41 PDT
One dextroamphetamine pill contains 5-15 mg of dextroamphetamine
sulfate. A low dose would be about 1 pill, or 5-10 mg. A high dose
would be around 120 mg. Typical doses range around 30 mg. Of course,
again, this depends alot on your own body metabolism.

You may also find the following table on cannabinoids useful, it is
slightly more detailed:
Cannabinoid elimination time (1 "time" = 1 joint)
1 time only 5-8 days 
2-4x per month 11-18 days 
2-4x per week 23-35 days 
5-6x per week 33-48 days 
Daily 49-63 days 

Feel free to continue asking for clarification.
