In this the fifth episode of our podcast Allison and I talk about acidifiers, both the 'good' ones that we give out in NSPs and the problems ones like lemon juice and vinegar

For links mentioned in the show, and a chance to watch the great citric acid video that is available free in NSPs please click though to the full article.

I've also included a YouTube rip of the Citric DVD that is available free from Exchange Supplies (you can get enough to give them out free to all the visitors to your exchange is you are getting your acidifiers from them). The film itself  includes two people well known to the UK drugs field, Andrew Preston from Exchange Supplies and Jenny Scott from Bath University, Jenny's team is one of the only ones in the UK with a licence to experiment with Heroin and Crack Cocaine.

Please let us know what you think of the show over on our forum.
