Smoked weed for first time in 6 years whilst drunk. started to freak out and have panic attack. been feeling out of it for 5 weeks now. weed laced?

Probably not, but: it's impossible to be certain. 'out of it' is not a usual effect w/o more extreme poisoning symptoms quickly. It's more likely you feel foolish for doing it and are obsessing. Try a week or so of very healthy living - food, rest, activity, companionship to restore yourself and minimize or avoid intoxicants. You should feel better soon. Best!
