It's like that down there unfortunately. I've only bought stuff to smoke down there once tho. I went to Club Colloseum in Vauxhall for a night out and bought some afghani hash on the dancefloor. The dude was off his face on pills or coke or some shyt. He walk off, then came back after a couple minutes, then pulled out what looked like an oz block of hash. He put it in his gob and bit me a piece of which I reckon was around 7-10 gram for £20. It lasted me at least 5 days and I smoke a fair bit. It was clean and the best random gear I've picked up while out of town
