Lolz.....@kevaton, funny question of yours...

Is our sixth sense now contingent on marijuana intake?

It'd take some studies to come up with a suitable response to that....lolz. Thanks for visiting.
But then, on a serious note.....It certainly hinges on what works for an individual. It is largely psychological too, because what works for you might not work for someone else. So, if 'pot' smoking induces a level of sixth sense for a person, then maybe that's their own creative trigger.
