anyone who says tolerance does not exist is a moron--not that any of us on this website are morons. it's a proven fact that our bodies build tolerance against drugs, among other things.

for example, a flu vaccine is just a small amount of the influenza virus injected into a person's bloodstream. the amount of the virus is so small that our bodies can effectively eliminate the virus, while building TOLERANCE to it. This prevents further symptoms when a person comes in contact with a full-blown influenza virus, it helps us to build immunity to the virus.

the body's defense mechanism is tolerance. THC doesn't naturally form in our brains. As we put the chemical into our body more and more, our body becomes more and more effective in removing, breaking down, and metabolizing the drug.

in my experience, the first smoke of the day is the strongest. why? becasue even sleeping is like taking a 8 hour (or in my case, a 12 hour) tolerance break

also, in my experience, i don't get that much more stoned if i smoke 2 joints in a row compared to 1 joint.
