Holly, I can vouch for horse riding being dangerous, though I never tried ecstasy. I know many younger folk who did, much to the anxiety of their parents. They're all now in their 30's, hard working, contented individuals, focussed on buying a home, having children - and keeping said children away from drugs
I had a very serous fall in my mid twenties, from a bad tempered horse who took a lot of pleasure in unseating his riders. Serves me right for thinking I could calm him down eh. But, there's a thought. I was in hospital for 5 days, endless X-rays etc, but their main worry was the concussion rather than the neck injury. I didn't get physio then (who knew it existed in 1974) but subsequently have had physio on the nhs for the residual problems in my neck. As we all know horse riding is dangerous, should we make folk who get chucked off, despite their best attempts to avoid this, pay for treatment.
I'm not defending those who indulge in excessive smoking, drinking, drug taking, and other health damaging practices. But, life is full of risks and dangers, its part of what makes us human to learn to negotiate our way through this. I don't support this idea, as I do wonder where it would lead us
