The Home Office responds to rumours of delays to the enforecement of the Psychoactive Substances Act 2016 via a published answer to a written question from Andrew Gwynne, MP. He wrote:
To ask the Secretary of State for the Home Department, when those parts of the Psychoactive Substances Act 2016 which have not come into force are expected to come into force.
To which the Home Office replied:
We expect to commence the Psychoactive Substances Act in its entirety in the spring. We need to ensure the readiness of all the activity necessary to enable the smooth implementation of the legislation across the UK and to support law enforcement in their ability to drive forward the legislation on commencement.

So, this confirms a tweet earlier this month from BBC's Mark Easton:
Govt's much criticised Psychoactive Substances Act delayed at least a month because of police fears over enforcement.— Mark Easton (@BBCMarkEaston) March 11, 2016
"Spring" is a bit vague though, considering the original date of April 6th is technically spring. Perhaps I'll put in another order for some more Salvia extracts after all...
