The respiratory system uses osmosis to interlace caffeine in the digestive system through your midi-chlorines

TIL that apparently I'm the only one that gets panic attacks from this combination.

Weed is not at all akin to coffee and many don’t get energy from it in any useful sense.

No, you see, the key is to use them together. The magic inside builds up like a volcano and you'll feel energy tingling in your fingers before you collapse and have a panic attack.
They say sativa is the energizing/focusing strain, and indica the relaxing/numbing.
- Which is a complete lie, there is no difference between a modern bud advertised as sativa and one advertised as indica, complete bro science.
  Different kinds and quantities of terpenes however can have an impact on the kind of effect you get.

I've had very little experience with weed, didn't take it with caffeine. Is that a thing? Does it feel different?

You're less sleepy?
Idk I live on caffeine and weed so my tolerances are... high.
- One of us. One of us.
- Its fun to do on a saturday and you have either nothing to do or a bunch of chores. A nice sativa with some coffee on a nice sunny day is pretty fun.
It is a thing. The classic name is the hippie speedball. I would say it definitely feels different, but I have ADHD so stimulants might work different for me than others.
It gave me ultra-focus and made me act autistic.
There's definitely a synergistic effect with the two, however the exact effect could vary. For myself it provides a quicker onset to the effects of weed, whilst maintaining the functional aspect of the coffee quite well.
I learned about Adderall from a guy on max Vyvance and Adderall that smoked an ounce or more per day. Dude played counter strike at god mode hacker level.
- An ounce per day?? That's insane on multiple levels, but just the cost alone... unless they're growing their own, that's an extremely expensive habit.
