If Marijuana Were Legal, Would Rehab Embrace It Like They Do Cigarettes?

I have a former relative in a drug rehab facility. When he went in, he was not a cigarette smoker. From what I hear, he has now taken up smoking, and the facility is discouraging him from trying to give it up. With tobacco, being the number one killer among drugs, I find this extremely counter-productive and just another one of rehabs hypocrisies. So if marijuana were to be legalized, would such a facility embrace this too? How is this not hypocrisy.
Sage… Your off topic and missing the point of the question. But…. just I so get this straight, are you actually suggesting that nicotine (a drug that kills 5.4 million people worldwide per year) is a safer drug than Tetrahydrocannabinol (a drug which there has never been one confirmed death) ? Your not really serious are you? If so, what’s your last name Benson or Hedges?
midnight. He was an in-law. There was a divorce. Therefore -former family member.
