ABOUT MARIJUANA
Marijuana is a Mexican term for the Cannabis (Indica, Sativa and Ruderalis -For detailed description we suggest you to take a visit to the Amsterdam Cannabis College) in many countries the term Marijuana means dried female Cannabis buds prepared for consumption.

The strongest Cannabis varieties are Indicas and Sativas. To name some strains:

Indicas: Afghani, Northern Lights, Shiva
Sativas: Haze, Swazi, Thai

Basically the Sativa produces an energetic uplifting high(clear head and body; communicative -the strongest sativas in some people may cause panic attacs) and the Indica produces a lay down stone(dizzy with slower movement; monged -the strongest indicas in some people may cause paleness and vomit). We said "basically" because there are so many subspecies of sativas and indicas with totaly different characteristics.

Many smokers prefer to smoke hybrids instead of pure Indicas or pure Sativas.
Hybrids are mainly divided into 3 categories: Mostly Sativa, Indica / Sativa and Mostly Indica.

Mostly Sativa
75% Sativa 25% Indica (Durban, Kali Mist, Neville's Haze, Power Plant, Purple Haze, Silver Haze, Skunk #1, etc...)
Indica / Sativa
50% Sativa 50% Indica (AK47, BubleGum, Jack Herer, Orange Bud, Super Skunk, White Rhino, White Widow, etc...)
Mostly Indica
25% Sativa 75% Indica (Blueberry, Buddha, Citral, El Nino, Great White Shark, K2, Misty, Northern Lights #5, etc...)

Just try a few strains of different categories and you

Go to the van gogh museum and the riljkstaat as far as coffee shops doesnt really matter which one you go to they all have the same stuff, the Hemp Hotel has good people hanging out and working there. Other then that Amsterdam sucks.

Look for information in

there is an interesting article aboot holland

Go straight to Sheeba on Warmoesstraat which is parallel with Damrak and two blocks over. This is a clean no nonsense coffeeshop with good weed & hash and staff who know what they are selling. A second choice is Utopia, particularly good for hash and over on Nieuwezijds Voorburgwal which is reached from Dam Square on the left heading down to Central station. The fun bit will be walking between the two !

The Nes is the best. Look for site on the internet.
