Hello, I personally can tell you pot does effect you. I smoked f/20 yrs. It effects your concentration, coordination , and mood.I would not recommend it for anyone in health care or anywhere else.I really had no idea how it truley affected me until I quit yrs ago. The mood swings and cravings are tough to get over. Its amazing how clear things become when your off of it for so long. I can have a drink on the weekend no problem,but with pot you have to have it ,or think you do. It really does take control,so please be careful if you use.If I had to do it over again I would have never touched it. I was a daily user and you have to have more and more to get the high, not to mention the expence. Thanks all and god bless.
