Yes, absolutely. For a first timer, a single drag from a joint is enough. If it's a spliff (weed mixed with tobacco, IMO makes the taste better), then maybe two drags, and you're all set for the evening.
Same as with other medicine, alchocol including. Water can kill you too, btw.
Next time try one small puff & dont keep it in you too much and see where it takes you, if nothing for 30min, try one more.
Another thing- it might be possible you already have preconditioned yourself mentally in a way that might be hard to get outside of, that'll cause anxiety even when thinking about smoking marijuana. I'd recommend trying "medicinal" first (ie. mostly CBD (ie. 20%), THC <0.5%) and then only progress to strains with higher THC content.
Also, you probably should see therapist anyways. Having psychosis is not a good sign. Most likely you have some other issues you need to work on.
"If you have problems using weed, weed is not the problem!" (c) :D
Uh, whoah there. I'm just gonna say, you're describing a general lack of impulse control and risk assessment here. This is a significant contraindication to inebriants of any kind.
Its important to note that alcohol and weed have exactly opposite effect on brain: where alcohol dulls you and make things matter less, weed can make you overly focus on your thoughts, more than a sober you would consider appropriate. This can lead to paranoia, because the first whif of it sends you on a spiral where you think about it, and that usually makes you even more paranoid. It is a form of mild psychosis. "The cur" is you have to realize that while your thoughts are valid and about real things (something real made you paranoid in the first time), the magnitude of your reaction is currently being altered by a drug. This allows you to take control of your emotions/feelings and allows you to logically reason about your current mind state.
This skill you _have to_ learn to overcome paranoia/psychosis on weed, and it is much harder to effectively practice while under weed influence. But on the other side, once you do, you can practice it while sober too, and that alone improved my mental health long term.
It is a psychoactive, and with high doses you can even start seeing your vision pulsate and shapes morphing. If you were hearing things and had psychosis, you definetly had way higher dose than you should have. If you try again, give yourself 15 mins between single puffs.
It's great for me though, helps with the suffering associated with chronic nerve pain.
But the first time I tried vodka it didn't go well either. I downed like 200ml in a blink of an eye and thought "this ain't go no effect" so downed another. Then another. And then ... came the effect. So maybe my first attempts at marijuana weren't a "glass of beer" but a "bottle of vodka" as an allegory.
