Smoke and Coffee

Saw a recent study on biological links between smoking and coffee (onlinelibrary.wiley.com/doi/10…)

Smoking and coffee have strong genetic connections, meaning it might be harder to quit one if you're a heavy user of the other. I also found out that coffee/smoke smell is part of why they're highly addictive because the smell contains chemicals that inhibits certain enzymes (MAOs) from breaking down neurotransmitters (the chemicals in our brain that helps us feel excited, happy, sleepy etc)

I wonder if there's a connection between the 2

well, signing off with "don't do drugs, kids"!
