If you live in the UK, most of them have been controlled drugs since 1977, when the tryptamine and phenethylamine derivatives paragraphs were added to the Misuse of Drugs Act.
However. According to KSwift 5-MeO-DALT is not covered by the misuse of drugs act for the following reasons: 1/ The tryptamine coverall paragraph refers to tryptamine (or ring hydroxytryptamines, and their ethers and esters) derivatives created by substitution at the sidechain nitrogen by alkyl groups only. As an allyl group is classed as an alkenyl group, it is therefore outside the remit of the paragraph.
2/ Alkyl cannot be taken to refer to any hydrocarbon chain (within the meaning of the act), as the coverall paragraphs for derivatives of pethedine (demerol) and fentanyl refer to alkyl, alkenyl or alkynyl group. Therefore they must be seen as distinctly different.
