Can I cross breed with other types of plants?

I was thinking because stinging nettles are one of the closest breeds of plants to Cannabis, maybe you could cross breed them. I know it sounds completely pointless coz lets face it who wants smoke that can sting you lol. But it's not illegal to grow stinging nettles in the UK, and if your Cannabis looks like them (Or any other weed that may cross breed with Cannabis)then your really doing nothing wrong, you may look a bit strange with a green house full of nettles but hey. So what you think? And has anyone tried this? And if so how'd it go?



Cheers and peace

Hope you have a PHD lol hey go for it cause I'm sure people have tried crazier shit...

im not sure doesnt sound safe or healthy to me. unless you have a plant degree and a medical degree i wouldnt advise you to smoke it! or supply it to anyone just incase it causes a chemical reaction in the human body

lol | think it just mite work, just dont know what weed to cross breed it with lol

And why I picked nettles was coz It's also used for medical usage as well as cannabis. Not the same medical usage, but still.

Or maybe cross breeding with hops? Still the same family, a bit big tho.
