2C-F , also known as 4-fluoro-2,5-dimethoxyphenethylamine , is a psychedelic drug of the phenethylamine and 2C families.[ 1] [ 2] It is taken orally .[ 1]
In his book PiHKAL (Phenethylamines I Have Known and Loved ), Alexander Shulgin lists the dose of 2C-F as greater than 250 mg orally and its duration as unknown.[ 1] At a dose of 250 mg, 2C-F produces slight and uncertain effects including possible modest closed-eye visuals and pleasant lethargy .[ 1]
Very little data exists about the pharmacological properties, metabolism, and toxicity of 2C-F.[ 1] [ 3]
2C-F may be found as a brownish freebase oil , or as a white crystalline hydrochloride salt.
The chemical synthesis of 2C-F has been described.[ 1]
Analogues of 2C-F include 2C-B , 2C-I , 2C-C , DOF , and 25F-NBOMe , among others.[ 1]
2C-F was first described in the literature by Alexander Shulgin in his 1991 book PiHKAL (Phenethylamines I Have Known and Loved ).[ 1]
Society and culture [ edit ]
As of October 31, 2016, 2C-F is a controlled substance (Schedule III) in Canada.[ 4]
2C-F is not an explicitly controlled substance in the United States .[ 5] However, it could be considered a controlled substance under the Federal Analogue Act if intended for human consumption.
