You are in for a big disappointment.
The legal weed shops have trash. Even the most expensive, highest THC content weed they offer is pure and utter crap compared to the real deal shit from the 90s.
Every strain you try, it's all the same dried up bullshit. It all smells like mold.
The old school shit is gone forever. It was bright green. It was sticky. You could press it against a car window and it would stay there. It would smell like real deal skunk. Super skunky. It didn't have all the stupid orange and red hairs nobody cares about. It was just pure bright bright neon green. And it looked like it was dipped in sugar, with the little glands glistening all over. It was soft to the touch and "doughy". When you pulled a bud apart, it was not porous like all the crap these days. It was squishy yet solid, and thick throughout the middle of it. You took a hit and it tasted so good, and then it expanded in your lungs and you had a fit coughing over and over.
The crap you get these days is dry and has a ton of airspace in the middle of it. It's overdried, yet mildewy. You take a hit and it tastes like shit, does not expand, and you only cough due to the harshness of it.
Or maybe, just maybe, there may exist a strain like what I used to get back in the 90s. If anyone that's knowledgeable reads this and knows exactly what I'm talking about above, and if a strain does exist today to match what I'm talking about, please tell me what it is.
