Photo – I have prehypertension in the day time, I'm not over wait. But at night i will consume a little INDICA strain only and my blood pressure will immediately go down to a very healthy set of numbers. This is proven every time i go for a night time rehi. i have a blood pressure machine at home and it shows me the differences very clear.. I recently went to the doctor for a physical,, i went after smoking indica strain and sure enough healthy numbers on his equipment. I can only imagine sativa strain bud will do the opposite,, maybe jack up your pressure. The kush at first will get my heart beat up but will come down fast if i relax deep.. the blood pressure numbers are low even when my pulse is up from the kush. Amazing break through!! Marijuana lowers blood pressure without a person having to take those horrible drugs! drug companies know this, so marijuana is kept demonized politically for the benefit of drug companies who lobby congress to have strict laws.
