Here you are:

And spend of your substance in the cause of Allah, and make not your own hands contribute to (your) destruction; but do good; for Allah loveth those who do good. (Quran 2:195)

O ye who believe! Eat not up your property among yourselves in vanities: But let there be amongst you Traffic and trade by mutual good-will: Nor kill (or destroy) yourselves: for verily Allah hath been to you Most Merciful! (Quran 4:29)

There is profound meaning in it. 1. All your property you hold in trust, whether it is in your name, or belongs to the community, or to people over whom you have control. To waste is wrong. 2. In 2:188 the same phrase occurred, to caution us against greed. Here it occurs, to encourage us to increase property by economic use (traffic and trade). 3. We are warned that our waste may mean our own destruction ("nor kill or destroy yourselves"). But there is a more general meaning also: we must be careful of our own and other people's lives. We must commit no violence. This is the opposite of "trade and traffic by mutual good-will." 4. Our violence to our own brethren is particularly preposterous, seeing that Allah has loved and showered His mercies on us and all His creatures.

I think it's clear. Smoking is prohibited. It harms those who smoke and those who are passive smokers. And it is waste of money at the same time. We spend money on what is damaging us and distract it from what deserves to spend more. E.g. family.
Greed is also a disease. The victims of the money-passion are not only the misers, but also those whose souls are hurt by their behavior. A passion can kill the body, the soul, or both. We cannot expose our and other's bodies and souls, to harm.
According to Islam the body is received from God as a loan which is only deposited with us. We cannot cause damage to the deposit.
I go further. Alcohol, a drug, is considered by Islam as a mind-altering agent, which restricts the freedom of the soul and enslaves it. Not only the drug but the status in that condition is also prohibited. The status under influence is not allowed if it is not the result of illness or juvenile life.
This is not about alcohol or drugs, but any influence that a child or patient cannot avoid on their own accord. These are exculpatory factors. In the case of a healthy adult who is not restricted in his/her consciousness, Islam does not tolerate captivity of awareness because it is a harmful to the soul.
Whoever creates for himself or for others such a condition, commits sin.
Nor can I, as a religious leader, create situations in which an individual is deprived of his/her free choice. If I give the chance for free choice, the issue of responsibility for the decision shifts from me to the subject. If I was not doing so, I would consider that faith is my own property and not of Allah, however I have no right to treat the means of Allah as mine. What I am entitled to is the teaching and offering an alternative to choose. Here is the dot at the end of the sentence.
It would be really a good question how can the brain-blocking communication strategies of today be judged from an Islamic perspective?
