why ask the question after the point?
i hope you have a benzo tolerance otherwise avoid any other CNS depressants such as alcohol, opiates, G, etc or you're significantly pushing closer to overdosing.
likely (hopefully without doing anything stupid, hurting yourself) you'll just pass out if you've no tolerance otherwise just feel the synergism between what the weed and clonazepam can produce. a nice buzz as it definitely takes the edge off a sometimes over-bearing edgy, anxious pot high.
