I don't find it weird at all. Cannabis is less harmful, less addictive, and subjectively, I find it way more fun.
Tobacco (nicotine) is hyper addictive to the point where people gradually get chemically compelled to smoke just about all the time. Arguably maybe caffeine is similarly compelling (I certainly drink caffeine all day), but most people consider caffeine to be pretty benign. Cigarettes are one of the hardest soft drugs to quit.
The long-term health effects of cannabis probably need to be studied more, but prohibition has actually made it harder to do just that. Now that the laws around weed have relaxed a little bit, it'll be much easier for people to legitimately do the scientific studies needed to show how cannabis affects the human body, how it affects the mind and mood, how additive it is compared to other common drugs, how it is typically used, and what effects legalization has on society compared to decades of criminalization.
The thing that I find truly weird, and actually pretty upsetting, is that I can stop by one of the many dispensaries around here and pick up weed flower or a 10-pack of cannabis gummies for like 15 bucks, but in other parts of the country there are people sitting in jail for less.
