question about smoking

So I havnt smoked in about 4 years yet im growing. I have 4 plants that are 2 1/2 weeks into flowering and are producing buds they are about 5 foot tall right now. My question is I really wanna try out one of my plants but dont wanna wait another 6 or so weeks. Can I pluck off a little bud? Will it grow back and will it be potent enough to do anything if smoked?

wait, its not even anyware near done.

no it will not grow back lol, and if you smoke it right off the plant it will have minimal THC, and most likely give you a killer headache and your guna have a bad impression of weed so wait till that shits dank, i mean you've already waited 4 years....

lol yeah kinda what I figured but i went from smokin every day to not smokin and now its so close to me lol.
