The thing is. Alcohol can be used in for example cooking. Cigarettes have no good purpose, nothing you can really do with them that has utility outside of direct consumption that exposes you to the full health risks.
And at that point I fear you're also diminishing the unique harm and danger of cigarettes which produce second hand smoke which exposes others, including kids to health dangers without their consent.
How about we slay the first demon here before starting to equate another lesser one with it? Most people do not have a risk of getting addicted to alcohol, nearly everyone has a risk with a few tries of getting addicted to nicotine and it's spreading like a plague among children with candy and sweets flavored cartridges for the poison that is e-cigs. This undoing a generation of progress.
It really does risk making more people dismissing the unique dangers and threat of nicotine and smoke products by equating the two and risks creating a DARE moment where the whole thing is just mocked by rising anti-science, anti-expert sentiment spurred on by capitalists eager to undo regulations. I mean things like this are catnip to people like RFK who want to torpedo evidence based science in favor of vibes and snake oil because it presents an in with your average person to criticize the health establishment over at least misplaced priorities.
Drinking on its own is a danger to the drinker. Only when done to excess does it endanger others. Smoking at all produces second-hand smoke and can encourage others to join an addictive behavior that is very, very hard to quit and will be a monkey on their back for years, decades after they stop whereas MOST humans can stop drinking alcohol with less ill effects than stopping daily consumption of caffeine.
Any amount of alcohol is a carcinogen and unhealthy, but at the same time we have to ask what level of risk is okay. Any amount of charred food cooked on charcoal is also a health risk for instance and can lead to exposure to carcinogens. The unique problems of cigarettes and nicotine were always impacts to others who didn't make that choice including children trapped with smoker parents as well as the addictive properties which left most users trapped or facing a hard fight to stop as well as bad behaviors by industry to hook people while they were young and down. Yes the alcohol industry also tries to get teens and young people to drink but nearly all of them can just stop after they leave college and go on to have a healthy life with zero or limited interactions with alcohol, you cannot say the same for someone who starts using nicotine and uses it heavily for even 6 months.
