People aren’t dying very young with tobacco addiction for the most part. There is cancer in youth sure , but tobacco is not the leading cause of that .
People who die of tobacco related illnesses are functioning adults and contributing members of society for the vast majority of their lives .
The disruption to the lives of drug addicts and their friends and family far exceeds those faced by tobacco addicts.
Not everything is a conspiracy or corruption people only react to what they see, the impact of drugs is far more visceral and immediate than tobacco or say obesity which kills even more, so pressure for legislation is higher
If tobacco killed because the of one wrongly cut cigarette you smoked , it would require prescription too
