Illegal/Dangerous Activities: Explicit "how to" discussions of illegal and/or dangerous activities, or posts advocating such activities, are prohibited; such as: how to make explosives, manufacture crack, steal software, hack into the CIA, ... The Physics Forum’s guidelines regarding “Illegal/Dangerous Activities” includes any discussion dealing with the isolation, purification and use of chemicals listed as List I by 21 CFR 1310.02 or controlled substances of any schedule (21 CFR 1308.11-15). Discussions dealing with the isolation, purification and use of uncontrolled chemicals listed as List II by 21 CFR 1310.02 or uncontrolled chemicals which have been associated with the illegal manufacture of controlled substances are allowed but will be closely scrutinized by PF staff. Examples of uncontrolled chemicals that meet these criteria include ammonia, acetone, potassium or sodium permanganate, lithium metal, sodium metal, potassium metal and sodium or potassium hydroxide. A complete list of List I and List II chemicals as defined in 21 CFR 1310.02 can be found at the bottom of this message. Discussions regarding home experimentation to isolate or purify List I chemicals and those chemicals associated with the manufacture of controlled substances and reactive ingredients in pyrotechnic mixtures is defined as a ‘dangerous activity’ in this Forum and is prohibited. The discussion of home experimentation to isolate and purify List II chemicals will be closely monitored by PF staff and may be locked or deleted for the reasons given above.
