I have no moral or philosophical problem with weed, and I indulge in
it occasionally myself, but I know it can be harmful to the lungs, esp. in
the amounts you're using.
Thomas has excellent advice on cutting back/eliminating the Lorcets. I recently went through a prescription of Lorcets myself and was terrified I'd have withdrawals, but I had none at all! I was lucky, I guess, though I was using a small amount for a short time.
