22. Nicotine strength
a. The maximum nicotine strength of eliquids allowed to be offered for sale on ECF
by Suppliers is 36mg or 3.6%. No liquid of strength higher than this can be specifically offered or specifically mentioned by Suppliers. Trade deals are exempt, within private supplier boards only, as higher strengths are needed for trade bulk mixing. Note that there are shipping restrictions in some countries for toxic materials, which can be obtained by application to your local Postal Service and private shippers, and you are cautioned not to contravene these restrictions.
b. Suppliers can sell whatever strength they wish with the exception of pure nicotine (900mg / 90% and above). Sites that sell pure nicotine will be blocked by ECF
. We define 'pure nicotine' as 90% / 900mg/ml or higher.
c. There is a limit on public discussion of 200mg (20%) maximum for mixing discussion, recipes and tutorials, and also in the Classifieds.
d. The use of 'Pure Nicotine' cannot be discussed (in detail) on public forums on ECF
(trade forums are exempt) due to the hazard  - see Notes below. That is to say, it can be mentioned in passing but not discussed at length especially as regards mixing.
 It has become obvious that some members joining in discussion of pure nic do not have any idea of the danger, or any knowledge of working with hazardous chemicals, or even any basic knowledge of measurements. Pure nic is as dangerous as cyanide
- opening a bottle in a room can result in all present being poisoned. It must be handled in a fume cupboard, with hazmat precautions. Pure nic can be theoretically defined as: Nicotine 100%, 1000mg, 1000mg/ml, but is more likely to be found as 998mg, 997mg/ml or 990 mg (99%). We consider anything over 90% / 900mg to be 'pure nic'. No discussion of use or links to suppliers are allowed.
There is a very real danger of death or hospitalization with this material and ECF
cannot support any publicity of its use or sources. There is no need to use it since far safer strengths are available for bulk mixing, such as 48mg (4.8% nicotine in PG
), 60mg (6%) 100mg (10%), and so on. To protect our members and ourselves we do not allow discussion or sources of anything over 200mg (20% nic) except within private trade forums. Trade promotion on ECF
cannot exceed 36mg strength. Vendor's sites can sell any strength up to 89% though we advise vendors to limit sales to 10% / 100mg/ml where possible. Sites selling pure nic will be banned.
