What do these symptoms sound like to you guys?

It’s my Dad…Now my Dad has done drugs since his late teen years, He’s now 50….Recently he hurt his back so he’s been off work, So I think he has maybe started doing more….He has always smoked weed, and snorted cocaine…But recently we have found foil where he keeps his drugs, so I was thinking he’s been doing a little somethin’ somethin’ else if you know what I mean….But we haven’t seen the foil lately….So I was thinking he might be having withdrawls…I’ve looked online everywhere tryin’ to narrow it down…So far it sounds like Meth, because my Dad likes the rush that drugs give you, not the kind that will slow ya down like heroin…He dosen’t think me and my sisters know about his drug use other than the weed..so he just claims he’s sick with the flu or something…But he won’t let me take him to the doctor, he dosen’t like doctors just like nobody else does so he rarely goes unless he really needs to because he’s really not feeling well..But to be feeling as bad as he says you’d think he’d go…Anyway here’s the symptoms he has…And please don’t report this, I’m very serious about this….I need to know whether this is just withdrawls or if he’s really, really ill…

Full Body Shakes, Not just shivers, much more violent than that.

Cold Sweats

Hot and Cold Flashes

Nose Running alot

Blackouts, It’s happend once, right after snorting a line.

Skin Turning Pale off and on

Slight Moaning and Talking like trying to calm himself down

Drinking alot of water, I’ve never seen anyone drink as much as I’ve seen him

Seeing Spot, he says he’s seeing spots like when you come inside after it being really bright outside.
