I live in the UK, and over here drugs like heroin and meth are illegal. They not only lead to behaviours that can put others at risk (consider the bus driver taking a big hit of heroin before his morning shift), they also ravage the body resources, depleting nutrients, and over time often leaving it unrecognisable. In addition to this their highly addictive nature helps proliferate their continued use.
In these superficial times, more and more people feel the pressures to not only look good, but to project an image of health and well-being, a sense that there are doing well in life. I'd even go as far as to say that even the form this projection takes has been codified to some extent, which has led to many people projecting themselves is very similar ways.
Constantly having to exist in this environment is depressing for some and they may turn to drugs to temporarily alleviate them of this reality. Drugs that can do the holy trilogy 1. Place us in an alternative pleasant reality 2. Ravage our looks and body 3. Are highly addictive and leave users in a terrible place when they finally return. It's like going to the Bahamas for 2 weeks and coming back to find that your teeth are mysteriously missing, but while you're in the Bahamas, you don't realise it and don't even need teeth in order to have a good time there. Which is why many people taking these holy trilogy drugs will simply stay on vacation for as long as possible.
Addiction isn't inherently bad in itself. I could be addicted to helping people less fortunate than me, or to the feeling of succeeding in business. But to be addicted to cigarettes (not nicotine), is a lose-lose-lose.
I make the distinction between nicotine and cigarettes because I feel that with the advent of vaping systems, issues such as stained teeth, increased risk of gum disease and aged leathery skin have largely been minimised, factors which play a crucial role in how one feels about one's appearance. Vapers get precisely what they want, without the bulk of the carcinogenic substances and damaging ingredients that steadily turn us into a population of Yodas.
The increasing worries of personal appearance in today's avatar age greatly impact upon our mental health. Looking good can feed into feeling good which then can feed into how we project ourselves, and so on. Cigarettes are anathema to this positive cycle. Some people may say state or even fight for the freedom to smoke cigarettes because we should all have the ability to choose our own destiny. If cigarettes were running for president I just don't see how anyone could bring themselves to vote for the fate it would promise the electorate.
"I solemnly promise to ruin your health. Increase your chances of cancer. Make you self-conscious about your teeth. Leave you smelling bad. Thin your hair. Decrease the circulation into your legs. Make you look gaunt and old. And I swear that from this day forth, you will want to stick with me through it all"
For me, endorsing cigarettes is like giving the thumbs up to erosion of the body and health, and not even being given a happy place to go to while you're doing it.
