Smoking And Fitness

I just wanted to know how to smoke pot once a week will affect my performance in daily jogging. Will it be harder to breathe (significantly if any)? And no it is not a stupid question because smoking pot once a week has no effect on you what so ever in other cases. Please do not post comments that I wish not to smoke without having at least one reason. I wonder if I should stop using a hose to go to a vaporizer. Thank you guys for your help!

If you're serious about fitness, then you really should be waived.

It does affect the opening of the air passages which certainly has a negative effect on your ability to breathe.
It also affects the functioning of your heart.

I have included one link below and if you're serious about the health affects so you can go from there.
