I'd tend to agree, the options in top post are written as such to make one answer callous and the other correct a assume because of OPs personal biases toward the subject.
Really as long as you can maintain safety, show respect for others and continue to follow the rules I'm honestly happy for you to do most anything that doesn't harm others ("I don't like the smell" doesn't count as harm imo) and respects site rules in order to have fun on your days/afternoons off then go bananas.
Frankly speaking when it comes to the recreational user I know more than a few "mates" who could use a half a joint to calm them down a bit to bring less aggression/unhappiness from their weeks to almost everything in their hobby life, airsoft included. Sites sell those bastards beers throughout the days which absolutely has the potential to make things far worse than weed ever could.
My prescription is only for Insomnia so I'd not really need to smoke up at a site ever but this countries draconian dogma toward something that is proven to be helping a huge gamut of conditions is a little nauseating/offensive?.
