well there is a difference between alcohol and drugs, myself i believe u are able to control your intake of alcohol a lot more than drugs, since ive never taken drugs im just assuming its more addictive. For starters alchohol and junk food are legal, whether pot should be legalised is another matter, i think personally it shouldnt, ive been to amsterdam and seen the affects.
I do drink alcohol, but i know my limits, never passed out or anything, and i only drink say once a month. Yes it damages your liver, but the liver is made to get any toxins out of your body, so small amounts wont do it much harm, obviously if your binge drinking every weekend, it does harm. However if u stop at the right time, the liver is the best organ to repair itself. It can be over 50% damaged and manage to repair itself. Your brain cannot, once u damage it, thats it. Maybe i shouldnt drink, but i know the facts about it and what im doing to myself, i know my limits. And i know in a few years when im older i wont drink anymore, i dont need it.
If u are smoking cigarettes its just as bad as drugs, people know the health risks and its ridiculous why someone would start that in the first place, and junk food is the same, people need self control.
As for prescription drugs, i suppose its up to the person how much u take. i only take painkillers when i really need to and antibiotics when ive been savaged by a cat. I suppose if u take painkillers in large amounts when its not really needed it is bad for you. We have this drug in the vets called Rimadyl, its a painkiller and anti-inflammatory, we use it mainly for dogs with arthritis. It causes kidney damage if its taken too much in large doses. Its just a decision u make, the dog is in pain constantly or u risk some kidney damage.
So im not saying drinking is right, i personally know what im doing and dont believe its enough to affect me when im older. smoking and junk food are both wrong but i believe drugs are so much worse than the other things. Its the first step onto a very bad road, it leads to harder drugs in a lot of cases, car accidents, loss of job, loss of friends.
