Ibuprofen and aspirin and others make your blood thin. How can it increase lifespan? Go start drinking 5 tablets per day of ibuprofen, I want to see how long you will live.

Very true facts bro, the prolonged use of the pharma's is what hurts you in the long run. Sure if you take Ibu for a headache a couple times in your life you will be fine.
But these drugs are not natural and can cause serious damage when taken daily or even weekly.

Yes marijuana harms your lungs when smoked in copious amounts but thats your choice, you can vape or eat edibles to take that negative effect away.
You can not due that with any of the aforementioned drugs.
