It looks like today’s marijuana is bringing a whole new definition to the term ‘pot head’.

Bro Bible – A new study testing the THC content of legalized marijuana in Colorado has yielded some surprising results, mainly that today’s strains of weed can carry a potency of 30% THC content or more, whereas the strains of yesteryear were typically well below 10% THC content (meaning the THC would make up less than 10% of the bud).

So does that mean that today’s weed is three times as strong as the marijuana from the 80’s? Well, yes and no.
