I am a legal medical marijuana user. I also have a marinol prescription. I am currently attending drug counseling and my Marinol has been accepted (of course) as a legal prescription. The problem is the expense. Can they tell the difference between the two in terms of strength. I was told that I would recieve only one test that can calculate the nanograms in the one year program. If I choose to use Marijuana at 20% THC do I have to be careful how much Marijuana I use so that they won't be able to tell that I am in fact using Marijuana. Should I press the Kief into pills of the same size and press on. Can they tell me that I am using too much "Marinol".
