Ganesha (2,5-dimethoxy-3,4-dimethylamphetamine) is a lesser-known psychedelic drug.

[citation needed] In his book PiHKAL, the dosage range is listed as 24–32 mg.[1] The drug is usually taken orally, although other routes such as rectally may also be used.

It is a particularly long lasting drug, with the duration listed in PiHKAL as being 18–24 hours, which might make it undesirable to some users.

It is named after the Hindu deity, Ganesha.
