Does anyone know how to properly clean a glass bowl used for smoking weed? - crack para eplan 1.9

All my friends were always caught with drugs or drugs .. I'm not really much of a smoker, I do not want to get rid of my plate .. quite expensive and is very beautiful it was .. I've heard that boiling water could cause cracks .. if someone can tell me how to clean, safe tap out in all things illegal, it would be greatly appreciated.
