Tobacco has nothing to do with controlled substances in the first place! Are you out of your mind?Tobacco is regulated by the federal government. The only reason tobacco and alcohol aren't scheduled is because they are -explicitly designated in the Controlled Substances Act- to be regulated by existing commerce laws. To say tobacco has nothing to do with controlled substances is objectively false.
I won't even address the assertion that "addiction has nothing to do with the molecule". Since a drug consists entirely of molecules, your claim doesn't make semantic sense.
I'll address this for you. When people refer to something as addictive, they either mean a psychologically habit forming activity (psychological addiction) or a substance that causes withdrawal symptoms when the body abruptly stops receiving it (physical addiction).
Most of US drug policy, in particular the Controlled Substances Act, is designed to curb the abuse of recreational drugs. Does this sound like its addressing psychological addiction or physical addiction? Keep in mind that not only tobacco, but also alcohol, the only recreational drug those withdrawal symptoms are lethal, are deferred to other policies in the Controlled Substances Act.
So clearly, the statement "addiction has nothing to do with the molecule" is referring to psychological addiction. You assert this statement is false. You are saying that psychological addiction is directly related to the composition of the elements used in the addictive activity. To be consistent with this logic, you must also reject the following claims:
"gambling addiction has nothing to do with decks of playing cards"
"video game addiction has nothing to do with executable code"
"sex addiction has nothing to do with penises or vaginas"
Surely you must realize that the majority of people who try physically addictive substances do not end up addicted. It does not make sense to say the chemicals involved cause the addiction.
