The nasal spray does not stop abuse but can be crucial in the event of a severe overdose.

- Other stuff is needed to stop drugs, but if you survive an overdose, you might get another chance to think about and consider putting down the drugs as well, says Mikael Andersson, who has previously been a drug addict.

While living in Stockholm, he met a friend who wished she had access to just Naloxan.

- She wishes it had existed earlier because then she might have been able to save her friend who unfortunately does not exist today, he says.

In the clip, Mikael Andersson and his friends at the drug organization "Våga Va" tell about the benefits of Naloxan.
