Grow them ... Sometimes you get some decent smoke ... They are expendable.
You can practice all the techniques on them ... LST , SUPERCROP , TOPPING , MAINLINING , LOLLIPOP , ETC.
The problem is that street swag / brick weed is rushed from the taco fields in Mexico .
They are NEVER fully matured bud. They spray God knows what on it.
It's usually some red hair Sativa strain ... Inbred plants .
Brick weed is cured rather sketchy ... Usually a compression cure ( heat ) . Bundled with sticks , shit , bugs and whatever. Most times hermie plants , fully seeded bag of crap you get for $5 on the street. Because they only grow to move product quickly and with crap cured weed you get that typical HARSH ass street smoke.
WHAT IF YOU GREW THEM AS THEY " SHOULD " BE GROWN ?
If you TREATED them like good seeds AND grew them out properly, cured the right way , you would get good smoke. These are kinda lanky Sativas and such so I would do some serious training on them . Sativas get better with longer flowering . Some can run real long ( 16 weeks ) but for shits and giggles you can grow them shorter with say 12/12 grows right from start. Expect 2 to 2 1/2 times at least in stretch.
Sometimes there are nice surprises with bag seed.
