You betray your ignorance (possibly fueled by your bias because of what happened in your family) on this subject by indiscriminately putting every "drug" in the same bag.

Some of those "drugs" are revered as great teachers in cultures thousands of times older than yours.

Most of those "drugs" are not addictive and are not harmful at all to health when consumed in moderation.

Meanwhile the two drugs that kill the most people worldwide by quite a large order of magnitude (tobacco, alcohol) are perfectly legal and widely available, to the benefit of government (tax) and corporation (amazing profits) alike.

Then there's a highly addictive, highly stimulating but not so harmful drug called caffeine that a large portion of the planet can't live a day without turning into an insomniac headache-plagued irritating hostile mess because they're all addicted to it.

But sure, responsible and occasional recreational drug use is the problem.
