I think this is a great find!

I'd add that this industry will also grow with the growing acceptance of "harm reduction" for intravenous drug users. With the fight against the heroin epidemic in the States, I've seen efforts to give out clean needles to stop the spread of infections (HIV, hepatitis, etc.)

Honestly, I'd like to invest in needle producers merely because I've seen first-hand the ravages of heroin in my own community.
