It's what I was told and tends to work out well. Though I'm not sure what a 1/2dram equals, it may be what the lines are. I've honestly never cared enough to find out.
I like to put a little olive oil (just a very thin layer) from the store on my counting tray. It has improved my 120 count oxycodone time by 17 seconds.
Counting trays now rarely used in UK. Majority of products are packed in cartons of 28 or multiples. Blister or alloy blister packaging is used. Speeds up dispensing and packs are relatively child proof.
We are trying to persuade govnmt to bring in original pack dispensing. This would stop snipping of strips and allow more automation.
