tension headache

[FunkyMonkey]

to be honest. the strain does have something to do with it

or type of bud

I remember when I used to smoke Schwag, I used to get headaches everytime I smoked it, since I was getting used to Chronic buds. But yea, dont worry. It might be the bud.

The only reason you would get headaches from smoking pot is from the addidives (ie, unflushed ferts, pesticides, herbicides etc. ) that some amateur or irresponsible grower used ;
or from smoking from a device that is leaking chemical compounds.
Clean Mj will not do this. It works on the body in the opposite direction.
It heals occular pressure. Its verifiable, measureable science.

peace.
