sugar tax
A pile of shit the UK government introduced in April 2018 in order to force aspartame and sucralose down our throats, due to their cheaper production than sugar it's convenient for companies to make, convenient for the government to promote the artificial sweeteners and most importantly to fool the nation into buying it (suppliers in small stores seem to sometimes drop regular drinks due to the tax shit, so it works)
Sugar tax is made to benefit capitalism and maximise profit and fuck over the people.
