DEAR GOD! Why so much mis-information? I will be very clear with this ..
When you smoke marijuana, you get high because it causes your brain to hemorage, well, all the excess blood that builds up on your brain is pused into the eye-balls, and since you puipils are pressed against the outer layer of your eyeball, it get pressed flat, making it look bigger... so, if you're ever smoking pot and notice your puipils get big - STOP SMOKING! Your bring is hemoraging! This is why chronic smokers are, um, "dim bulbs" if ya know what I mean..
You can alleviate the inner-crainial pressure one of two ways -
1) Drill into the skull to let some blood out - definitly not a favorite option ..
Or
2) Inject a little heroin - you will notice that heroin causes the pressure to LESSEN, making your pupils smaller, as it gives your brain more room to function...
