The partner of the late rock star Stuart Cable is leading a new campaign for stronger warnings on alcohol packaging.
The former Sterophonics drummer died in June 2010 when he choked on his vomit after a weekend of heavy drinking.
Think Before You Drink is aimed at bringing alcohol labels into line with stark warnings on cigarette packets.
Rachel Jones said phrases like "enjoy responsibly" did not adequately reflect the dangers of alcohol.
"Prevention is better than cure, and there's no cure for death," she said.
Speaking to BBC Radio Wales, Ms Jones revealed that she approached the Llanelli MP Nia Griffith following the death of another close friend at Christmas.
The MP agreed to raise the issue of alcohol labelling in the House of Commons.
Responding to Ms Griffith during Prime Minister's Questions, David Cameron referred her to plans to introduce minimum pricing for alcohol.
Ms Jones said this was missing the point they were trying to make about the need for stronger labelling, claiming it was "hypocrisy" for cigarette packets to carry warnings that smoking kills while the messages on alcohol were much milder.
"If you saw someone drinking a bottle of poison or bleach you would stop them," she said.
"People need to be aware that alcohol - in particular spirits - can lead to death."
She said the death of Cable showed the potentially fatal consequences of drinking a large amount of spirits in a short time.
"Stuart was getting ready for the Download festival and the guys in the band [Killing For Company] were all getting gig fit," she said.
"There are these diets which say a vodka is better than half a lager because it's lower in calories.
"He just switched his drinking habits... obviously he didn't realise that drinking a huge quantity [of spirits] in a short amount of time was going to have the effect that it did.
"People that do this may as well hold a loaded gun to their head because it will kill you."
Ms Jones has also secured a meeting with UK Health Minister Anne Milton in London in March to discuss the issue.
