NEW TO DRINKING BUT CAN HANDLE IT TOO WELL?!

So to make a long story short, I don’t drink alcohol at all, but I have a history with marijuana along with a medical card for it from Pennsylvania, and what one would call a semi severe addiction to amphetamines (prescription only) + Xanax. To be clear it has been at least a month or two since I have taken any prescription drugs. I haven’t smoked in almost about a month, my dad is a very heavy drinker and was at the time when I was born, so maybe genetics have a factor?

Also I never drink, like ever, I got drunk 5-10 times in the last 7+ years. Consumed alcohol maybe a dozen times, 15 at the absolute most, in the last 4-5 years to be honest.

I drank 4 fireball shots (Cinnamon, the malt liquor, not fireball whiskey) + 1 Kentucky burboun shot + + 300-325ML of 40% Blue Agave Jose Cuervo last night. For context, I did not blackout, or have a hangover and felt good (started drinking at 12:15am slept @ 6:30am) and only got 4 hours of sleep or less.

Today, I consumed about 275-300ML of the other half of Jose Cuervo tequila, and am curious as to why I can handle so much without being overly drunk or blacking out when I don’t have a tolerance, is it genetics? Is it the kind of liquor? I have so many questions and I know I’m in the right place to ask… thank you! Plz comment!
