I take it back. If you can ride a motorcycle drunk I'll sleep soundly as you drive!!
I can... but if you honestly trusted me under such conditions, I'd call you a ******* idiot for it!!
It's one thing to put yourself at risk but another thing to put others at a risk.
And that's the crux - The OP's guy
is putting others at risk.
To quote the post above, tolerance does play a big role.
OK, so what's the test, then?
What's the easy and reliable test I can administer to my staff, by which I can discover their own personal, specific tolerance levels to a given susbtance... before then applying the other easy and realible test to measure how much substance they've taken against this established tolerance level?
Yes, tolerance is a factor and you're absolutely right about all that...
BUT - until you can pin down exactly what that is in practical terms, for each and every single individual, you have no argument beyond unusable theory and instead are stuck with simple cover-all laws and a blanket zero-tolerance policy.
This applies to alcohol and other substances too, incidentally, and while my father could down two bottles of Famous Grouse before his driving was impaired to any extent that people would notice, he would still be driving WELL over the legal limit and subject to the fullest extent of the law if ever he had gotten pulled.
If they've really over done it, the feeling of being stoned is akin to that of what must be like paralysis. The effort to move, even slightly, is huge. I think this is caused by blood rushing from your muscles to your arteries for whatever reason, and in turn giving that pale complexion, commonly known as 'whitey'. If the effects continue then they'll need to lie down and pass out. Otherwise, nausea sets in and they're vomiting all over the place.
Yes, and accidents can happen. Gear can turn out to be stronger than you expected, especially a new batch from a different supplier. You can mis-measure or something just as easily. Any number of things can happen, and I've known several my own self.
Either way, you're lying immobile, outright unconscious or stuck curled around the toilet as a direct result of your drug use... meanwhile there's an emergency or something going on with one of the kids for whom you're responsible, and you're thus negligent.
No argument about tolerances would matter at that point, and in seeking to mitigate or eliminate the risk of such things happening it is far easier, simpler and fairer to just ban employees from drugs.
However, I generally stand by what I said. To someone with a high tolerance, or even just someone who knows their limits, the above just doesn't happen and nor does it dull your senses.
Yep, absolutely right - It "just doesn't happen"... until the day it
does. I've heard such claims from people quite often and almost every one of them has subsequently had to eat those words at least once.
