Frankly, the article doesn't do it for me. I find the whole "my drug is better than your drug" argument tedious. Tobacco is a drug. Get over it. Tobacco users are not inherently morally superior to drinkers or marijuana smokers or whatever.
This. All drugs are drugs, nicotine and tobacco included. It is how they are used, how often, by whom, and at what time that make all the difference.
Are some quantitatively less risky than others? Sure. But they all present some measure of health risk ranging from miniscule to significant based on the above variables.
Are some of those risks misrepresented with some drugs more than others? Sure. But the bottom line is that you can smoke a cigarette or do heroin once and you'll probably be fine. Do either one ten times a day for your whole life, and you will likely die earlier than you would have otherwise.
Or maybe you won't. Roll the bones...
I get his frustration though. No use of any kind is going to be one size fits all from an education/prevention standpoint, and people like to err on the side of goal zero.
