The exact way that gemfibrozil works to reduce cholesterol and triglycerides (types of fat) in the blood is not known. High levels of fat in the blood are associated with an increased chance of heart disease, strokes, and other illnesses.

Gemfibrozil may increase the effects of drugs similar in class such as vastin cholesterol lowering drugs, which could lead to dangerous side effects.

I am a medical student currently working for a chain Pharmacy as lead certified technition. Unfortunatly since Marijuana is a schedule 1 drug there has been very limited testing with being affected by prescriptions. I would say there is a very small chance of your Lopid affecting the marijuana in your body as it doesnt affect your metabolism.

Dronabinol (Marinol) is an orally active cannabinoid, one of the active substances in marijuana. It increases drowsiness when taken with other drugs such as sedatives, antihistamines, muscle relaxants, and anxiety medicines. No known interactions are seen when taken with Lopid (gemfibrozil).

Good luck with your test... keep on toking..
