I do not in any way support the indiscriminate use of marijuana, but for so long have heard arguments for and against it's use. The debate still confuses me. A customer visited me only yesterday, and I was shocked at his appearance. He had lost a considerable amount of weight and looked frail and unwell. I had been told by one of his friends that he was "lighting up" and really taking it overboard. Mind you the friend is also a user of the drug marijuana, but from all appearances he looks in good form and health. I could not help but comment about his change in appearance and once that conversation got going he proceeded to educate me about all the benefits of the drug. I listened but still wanted to know by the end of conversation, why a drug that was so good for him was making him look so very bad. Help me understand it.
