True, you should wait until you're 15 to try coke.

On a more serious note, that's quite a biased way of thinking about cocaine use. The plant/substance doesn't have the same stigma in, say, Peru, where a 13-year-old is quite likely to have chewed coca leaves or drunk coca tea on many occasions. The perception you have of cocaine use is very much a product of the community in which you were raised.

What do you mean by ‘normal’?

If you mean healthy and what I would suggest for a teen, no. If you mean something that happens fairly commonly in the world, yes, that does.

Stop posting extreme hyperboles all around the discussion, please

Obviously it was hyperbole, but OP was sloppy when they stated "it is perfectly normal for people to experiment with substances when they come of-age.". What are young people (13 year olds? 18 year olds? 20 year olds?) and what drugs (just weed? any drugs?)? Others chimed it and argued that kids naturally alter their consciousness by spinning around and nobody thought to clarify.

I don't think it's natural for kids to smoke marijuana. It is something that SOME kids do, but it is not natural or inevitable, and it is categorically not good for them (from a brain development, mental health, time-waste and addiction standpoint). There is a tendency for people to minimize marijuana risks and get sloppy around pot usage by kids.

HN guidelines state that you should assume good faith, so nope, they most probably did not mean 12 year old kids doing heroin.

Nobody said that smoking marijuana is natural, the argument was that the desire to alter one's mind and to experiment is natural.
