I'm afraid it's too inefficient.

First of all, you're using an ENUM for a SINGLE variable

pawn Код:

enum cInfo
{
bool:CanUseCheats
}
new Cheats[MAX_PLAYERS][cInfo];

CAN simply be

pawn Код:

new bool:CanUseCheats[MAX_PLAYERS];

ANND

pawn Код:

public OnPlayerText(playerid, text[])
{
        if(strcmp("lxgiwyl",text,true,1) == 0 &&  Cheats[playerid][CanUseCheats] == true)
        {
        GivePlayerWeapon(playerid, 5, 1);
        GivePlayerWeapon(playerid, 22, 999);
        GivePlayerWeapon(playerid, 25, 999);
        GivePlayerWeapon(playerid, 28, 999);
        GivePlayerWeapon(playerid, 35, 999);
        GivePlayerWeapon(playerid, 18, 999);
        CheatTD(playerid);
        return 0;
        }
}

Can simply be

pawn Код:

public OnPlayerText(playerid, text[])
{
        if(strcmp("lxgiwyl",text,true,1) == 0 &&  Cheats[playerid][CanUseCheats] == true)
        {
        cmd_lxgiwyl(playerid, "");
        return 0;
        }
}

ALSOOOOO

pawn Код:

stock CheatTD(playerid)
{
        TextDrawShowForPlayer(playerid, cheattd);
        SetTimer("EndCheat", 5000, false);
        return 1;
}

IS PLAIN WRONG

because

pawn Код:

public EndCheat(playerid)
{
        TextDrawHideForPlayer(playerid, cheattd);
        return 1;
}

has a parameter.

And using TIMERS with parameters requires you to use SetTimerEx

SOOO

we change

pawn Код:

stock CheatTD(playerid)
{
        TextDrawShowForPlayer(playerid, cheattd);
        SetTimer("EndCheat", 5000, false);
        return 1;
}

this
to

pawn Код:

stock CheatTD(playerid)
{
        TextDrawShowForPlayer(playerid, cheattd);
        SetTimerEx("EndCheat", 5000, false, "d", playerid);
        return 1;
}

BUT, I do like the idea of implementing the single-player cheats like this using OnPlayerText.

Some points I'd like to see improved -

Better indentation
Usage of array's
custom cheat ID's
permissions for using EACH cheat SEPARATELY for each player
