Ok so I used to live in Houston and never really liked coke when I lived there.... I always thought it didn't effect me since im adhd and went through high school without it..... However I recently moved to West Texas to go to college and I'm about 30 minutes from the mexican border.... Anyway, about a month ago my friend showed up at my house with a 20 of coke.... thinking how I always had I was like w/e and did two Huge lines about .2 grams total (half the bag)..... Bam it freakin floored me.... I was trippin pretty good for about an hour and then smoked a bowl and passed out.... Yesterday I decided to go all out and buy an 8ball, which runs about 120 down here.... it was rocked out well and the guy I bought it from had already bagged it into 20s and 10s.... It's just as strong as the shit my friend had, and I have come to the conclusion that the coke in houston was really cut.... upon further research I found it's only about 5-10 percent once it gets about 200 miles from the source..... I did some tests on the stuff I got here, and with some help from my step-dad (who used to be a big cokehead) discovered it's about 75 percent pure.... That's almost unheard of anywhere else and I wanted to get some other input on the avg purity of coke in other cities, It may be worth my while to do some investing if the profit would be good LOL
