Mae adroddiad diweddar gan gonsortiwm o ymchwilwyr, gan gynnwys Figure 8 Consultancy Services Ltd, Prifysgol de Cymru, a Phrifysgol Glyndŵr wedi dangos y byddai’n annhebygol y byddai cyflwyno isafbris uned am alcohol yn peri i yfwyr newid i sylweddau neu gyffuriau eraill. Bydd hyn yn rhywbeth sy’n cael ei fonitro’n agos ar ôl i’r ddeddfwriaeth gael ei gweithredu.
A recent report from a consortium of researchers including Figure 8 Consultancy Services Ltd, the University of South Wales and Glyndwr University has shown the introduction of a 50p minimum unit price for alcohol in Wales is unlikely to see drinkers switching to other substances or drugs. This is something which will be monitored closely once the legislation is implemented.
