I used MMJ daily for well over 2 years straight and stopped in Mar. of this year. I had a fairly high tolerance, and could easily go through a goodly amount of bud, daily. Fortunately, back then I grew.
Been off it 100% since March, and today am going to renew my Med recommendation. I did smoke a bowl with a friend the other night, and just a couple hits had me stoned for hrs.
IF YOUR HEALTH WON"T SUFFER, I don't think there is anything wrong with a break now and then to allow some of the cannabinoids to depart the body (most importantly the liver, IMO).
Or, like said above...just change strains once a week...
