I'd be concerned about the addictiveness with alcohol. But I sympathise with your predicament & I can only hope that the law changes sooner rather than later & real cannabis becomes as cheap & easy to get as cannabinoids. Have you considered growing it yourself? The lighting & other requirements are becoming better & better value, & technological advances in both equipment & seed quality improve the ease with which fucking good weed can be grown, in very small spaces. Apparently. I'm not one to talk. While I can barely afford a cannabis habit, I am inclined to buy it from people who already know exactly what they are doing. One day however, I shall take the plunge & cultivate a little of my own, to save cash. Give it some thought, if it's practically possible...
