People complain about being sent to jail for weed as if this they are suffering a political persecution, but people can get in legal trouble for drinking alcohol in public places or illegally producing or selling it as well. In some European countries, if both parents are caught drinking alcohol at the same time, even just beer, they'll be stripped of their parental rights. Imagine if that would be a law in America for people who smoke weed. This would be called a genocide or something along the lines of political persecution, some absolutely laughable arguments.
Cigarettes are straightforward evil and harmful. The usage of tobacco is extremely idiotic, it was normalised and promoted by the tobacco companies for profit, despite all the known negative effects.
Gambling must be strictly forbidden. It's pure evil and it's only harming both people and society. In America, gambling isn't freely available to people, same as in many other countries. Try to run a casino in your back yard and get to enjoy the company of some handsome guys in blue. Is it oppression?
Sugar should be limited, same as many other harmful components used in the food production. Excessive usage of sugar leads to obesity which again, is bad for everyone. European countries pretty much do some really good job in this regard.
I'm really annoyed by the hypocrisy of people who so eagerly try to promote and normalise weed as if this is going to help everyone. It wouldn't. I really wouldn't want to see my children smoking it, offered by some chavs who would be friends of their friends I would not approve because of their low behaviour. Weed is same bad as alcohol, nicotine, gambling and sugar you mentioned. It slows down intellectual development of children and degrades the intellect of adults as well. Yes, weed can be a good antidepressant or a pain-relieving medication - if consumed for a short period of time and strictly when it's necessary. This whole hysteria with legalisation of weed reminds me of tobacco companies aggressively promoting cigarettes through the media back in the previous century or modern pharma peddling opioids.
