@Lustig Andrei,
That is good advice.
In my younger years I got into the habit of extensive cannabis smoking to the point where it made it hard for me to function properly in everyday life. That taught me how important moderation is, and how important the difference is between using and abusing drugs.
But for anyone who turn to drugs as a solution to anything, I would stress to them that to most problems that can be alleviated by a high, drugs are a temporary solution that cause more problems in the long run than they solve.
