How do i change the contrast/brightness of the player's screen?

When a player type: "!drug", his screen will change contrast and brightness.
I need a code about this, if someone can help me it will very nice

Take a look at the Draw* global functions on the wiki, for example this one:
https://wiki.garrysmod.com/page/Global/DrawColorModify

Also look at the Source Code for Post Processing effects from Sandbox.

Thanks very much. I will look.

you're missing an end), read the lua errors, that's useful

[SrAlfaceBR]

hook.Add("RenderScreenspaceEffects","isAlive?",function()
local cm = {
    ["$pp_colour_addr"] = 52,
    ["$pp_colour_addg"] = 1,
    ["$pp_colour_addb"] = 2,
    ["$pp_colour_brightness"] = 3,
    ["$pp_colour_contrast"] = 4,
    ["$pp_colour_colour"] = 1,
    ["$pp_colour_mulr"] = 1,
    ["$pp_colour_mulg"] = 2,
    ["$pp_colour_mulb"] = 4,
}
if !LocalPlayer():Alive then

     DrawColorModify(cm)

end
end)

Sorry, i didnt paste all the code. There is, don't works.

Please look up basic Lua tutorials before you start messing around with Lua, it will help everyone involved save some time.

You fucked up writing
Alive()

Now do everyone a favour and go watch some Code Blue videos.
