RE: deer cocaine??
I have used a home made mix deer cocaina and others.
I have used them all with equale good luck.
I have7 mineral licks on the farms I hunt
Most of them the deer have dug out a hole to get the mineral and salt
I don't hunt over them
I put out mineral out in the winter and again in mid summer ( easy axcess)
I find most of time I get more use of the licks in the late winter thru early summer.
IMO the mineral licks help the deer grow a better rack and help the does with the needed minerals.
