hello I modified the script so that it can be used with an item 

cl-vape 165 insert

if IsControlPressed(0, Config.RestingAnim) then
    Wait(Config.ButtonHoldTime)
        if IsControlPressed(0, Config.RestingAnim) then
            TriggerEvent("Vape:VapeAnimFix", 0)
        end
    Wait(1000)
end

cl-vape 184 insert

DrawText3d(pedPos.x, pedPos.y, pedPos.z+1.08, "~c~Hold ~b~\"ALT\"~c~ to store the vape.")

sv-vape replace her

if Config.VapePermission == true then
    RegisterCommand("vape", function(source, args, rawCommand)
        if IsPlayerAceAllowed(source, Config.PermissionsGroup) then
            if (tostring(args[1]) == "start") then
                TriggerClientEvent("Vape:StartVaping", source, 0)
            elseif (tostring(args[1]) == "stop") then
                TriggerClientEvent("Vape:StopVaping", source, 0)
            elseif (tostring(args[1])) ~= nil then
                TriggerClientEvent("chatMessage", source, "^1 Vaping: Error, Wrong Command must use /vape <start/stop>")
            end
            if Config.Debug then
                if (tostring(args[1]) == "fix") then
                    TriggerClientEvent("Vape:VapeAnimFix", source, 0)
                elseif (tostring(args[1]) == "drag") then
                    TriggerClientEvent("Vape:Drag", source, 0)
                end
            end
        else
            TriggerClientEvent("chatMessage", source, Config.InsufficientMessage)
        end
    end)
else
    RegisterCommand("vape", function(source, args, rawCommand)
        if (tostring(args[1]) == "start") then
            TriggerClientEvent("Vape:StartVaping", source, 0)
        elseif (tostring(args[1]) == "stop") then
            TriggerClientEvent("Vape:StopVaping", source, 0)
        elseif (tostring(args[1])) ~= nil then
            TriggerClientEvent("chatMessage", source, "^1 Vaping: Error, Wrong Command must use /vape <start/stop>")
        end
        if Config.Debug then
            if (tostring(args[1]) == "fix") then
                TriggerClientEvent("Vape:VapeAnimFix", source, 0)
            elseif (tostring(args[1]) == "drag") then
                TriggerClientEvent("Vape:Drag", source, 0)
            end
        end
    end)
end

by that

if Config.VapePermission == true then
    RegisterUsableItem('vape', function(source)
        local xPlayer = ESX.GetPlayerFromId(source)
        TriggerClientEvent('Vape:StartVaping', source, 0)
    end)
end

sorry my english its no perfect
