Tobacco

Negatively.
Less oxygen to muscles means lower performance which means less gains.

Of course the amount you smoke is a huge factor. 1-2 a day won't have a giant impact, but 5 or more probably will.

You should quit. It was the best thing I ever did in terms of getting pussy and feeling better/better gains. Smelling like dog shit and feeling wired isn't good for you.

It's bad for your gains. Even small doses of nicotine increase your heart rate by 10 - 20 points for several hours after intake, so basically all day long for a regular smoker. The smoke impacts your lung function negatively, even if you just started smoking. Not to mention what happens long term. Which leads to a worse oxygen supply, which in turn means less energy for your muscles. At least switch to vaping if you can't stop. Preferably you shouldn't take nicotine either though.

Nicotine is an aromatase inhibitor, decreasing amt of test converted to estrogen

nicotine is good for gains as an aromatase inhibitor, it also has powerful nootropic functions which positively benefit cognitive output

tobacco, from which most people get nicotine will kill you however
