Bad weed has nothing to do with this... I literally smoke shit quality to the 10 out of 10 dank... When your in a growers community, after a while you meet a bunch of people who grow. For example, right now, I grow, and I know 5 others who grow. We all trade each other weed. Now, 1 of my buddies is a horible grower... but he loves to do his thang, so we all let him be happy. However, he gives me ounces of this horrible shit that literally reminds me of mexican bamber.. Regardless, I still smoke at from time to time out of boredom, or when im low of my better quality stuff. The only difference of the effects of good weed and bad weed, is it takes more of the bad weed to get you high... THATS IT!!! Sure the taste my be way worse, and the harshness, the smell etc, but Smoking bad weed wont kill you, or give you panic attacks... It's all in your fuckin head... Weed is weed, the quality just depends on how and what type of high you will endure. Keep in mind, everyones brain works differently.. This 10/10 weed may be perfect for me, but may make the next guy have a panic attack. Or vise versa, one guy may love shitty weed because it gets said person high easily and for cheap.
And doesn't like the 10 outa 10 dank because its too strong. Or 2 diff people could smoke the same strain, same quality, same amount, and still have completely different euphoric experiences.. Or the opposite of euphoric.. You have to try little by little, get use to it, then you start to find your balance. Good luck yall!!
P.S. please wait till yall are fuckin 18... Especially since that fact your guy's brain is still developing. I mean I don't want to go and say weed will make you dumb, as Ive been smoking non stop since I was 14. However, the rate in which you can comprehend and imprint permanent information into your brain will be debilitated... Regardless, just wait till your legal lol! Not sure where your from, but regardless of a recommendation its illegal for all persons under 18 in my area.
