Bear in mind that some people are just less affected by some toxins.
Also, if you used those substances when you were younger, your exposure
may not have been long enough.  Notice how some five-pack-a-day smokers
are still puffing away at ninety, while others quit at thirty and still
die early.  Some people are just less susceptible.  It doesn't mean
certain substances aren't actually toxic.
