Won't be tested: You can't be tested for illegal drugs without your consent. This isn't the place to debate the wisdom of our cannabis laws, but until they change, perhaps you can go through life without taking medicines that make people even goofier than we are already. I also hope you do not experiment with illegal substances -- the warnings you've heard about them are actually true. Best wishes. ...Read more

How long does marijuana stay in your blood?

Up to weeks: The stuff also enters fat cells and may stay detectable for a long time especially if you're burning fat. One of the ironies of mandatory drug testing is that drug-users know marijuana stays detectable longer than the far more dangerous illegal drugs, so on friday night people decide to use intoxicants that are far more likely to do harm. Why not be "high on life" for now? ...Read more

Depends: Drugs are rarely looked for in blood tests - the preferred testing is of urine. Doctors usually do not do drug testing for a routine physical, and if they were, they would get urine either instead of or in addition to blood. It is never the wrong time to quit smoking, especially of tobacco, and you need to consider whether the marijuana is a problem as well. Talk to your doctor. ...Read more

When you donate blood- can they identify marijuana in it?

We won't look: Even if you believe our marijuana laws are wise, nobody cares whether there is a little bit of the stuff in blood for transfusion. It is hard enough to get people to donate blood at all without their having to be busted for weed as a result. Thanks for your being willing to donate blood, and don't worry about our "war on drugs" in the privacy of a blood donation. ...Read more

How long does it take marijuana to get out of system for blood test?

How long does it take marijuana to get out of system for blood test?

It depends: How long marijuana is detected in the urine depends strongly on frequency of use. In regular users (more than once a week), the marijuana metabolite builds up to a high level, often on the order of hundreds of nanograms per milliliter (ng/ml), from which it may take weeks to decline back below the threshold of detection. The situation is different for occasional users (no more than once a week). ...Read more
