One of the characters in this episode thinks he's just smoking weed. Here's the full 'dope' on what was in the weed and how it's supposed to handled;Parathion.To assure human protection the end user must wear protective gloves, clean protective clothing, and a respirator of the organic-vapour type when handling this material. He/she should bathe immediately after work. Industrial safety during the production process requires special ventilation and continuous measurement of air contamination in order not to exceed PEL levels as well as keeping personal hygiene. Frequent determination of workers' serum acetylcholinesterase activity is also helpful in regards of occupational safety, because the action of Parathion is cumulative. If an area of the body is contaminated with parathion, if possible, it should be removed immediately. Also, atropine may be used as a specific antidote.   See 1 other reply
