I don’t think it has anything to do with how the bud was cured. It could be the general overall strength of the herb.
However it is also likely you have just developed a tolerance. You could very well get the same feelings again with much stronger or maybe a different strain of herb than what you are used to smoking.
You can also try quitting for a while, this will make your tolerance go down and when you do smoke again you will notice a big difference. Another thing to try is eating a bunch of mango about a half hour to a hour before smoking, there is an enzyme in mangoes that can make your body more sensitive to the THC and reduce your tolerance. Also lots of exercise between smoke sessions tends to help your body flush out built up THC in your body and so your tolerance will be lower next time you smoke.
