The Western Himalayas is a major landrace cannabis cultivation region spanning the mountain valleys of northern India, encompassing traditional charas (hand-rubbed hashish) producing areas in Himachal Pradesh, Uttarakhand and parts of Jammu and Kashmir. ^[1] ^[2] ^[3] ^[4]

In the Western Himalayas, landrace cannabis is cultivated by local communities and also occurs naturalized across steep valley systems from the Himalayan foothills (~300–600 m) through mid-elevation temperate valleys (e.g., Malana, Kullu, 1500 m through 3200m) to cold-desert basins above 3,000 m; published records extend to ~3,500 m in Lahaul–Spiti. ^[5] ^[6] ^[7]

The region's cannabis populations are cultivated primarily for charas production, with hand-rubbing techniques passed through generations of farming communities.

Himachal Pradesh

Kullu District

The Kullu District contains the highest concentration of documented growing areas in the Western Himalayas:

Mandi District

Seraj

Kinnaur District

Lahaul and Spiti District

Due to the harsh climate and short growing season, as of 2015 is sparse evidence of current, intentional cannabis cultivation in Lahaul and Spiti districts. There are, however, feral, self seeding cannabis populations found near roadsides, rivers and temples throughout the district. ^[8]

-==Geography and Climate==
+== Geography ==
-===Topography===
+== Climate ==
-The Western Himalayas growing region occupies the middle-elevation montane zone of the [[Himalayas|Himalayan range]], primarily within the watersheds of major river systems including the [[Beas River|Beas]], [[Tons River|Tons]], and [[Alaknanda River|Alaknanda]] rivers. The region is sandwiched between the [[Pir Panjal Range]] to the west, the [[Great Himalayan Range]] to the north, and transitions to the [[Eastern Himalayas]] at approximately 80°E longitude.<ref name="Singh2005">Singh, S.P. & Singh, V. (2005). "Vegetation of the Himalaya". ''Mountain Research and Development''.</ref>
-Cannabis cultivation occurs primarily in:
+== Cultural Context ==
-* River valley floors (1,500–2,200 m)
-* Mid-slope terraced fields (2,200–2,800 m)
-* High valley settlements (2,800–3,500 m)
-===Climate Patterns===
+== Ethnic Context ==
-The region experiences a temperate montane climate with distinct seasonal patterns:
-'''Summer Monsoon''' (June–September): Heavy precipitation from the [[Indian monsoon]], with annual rainfall ranging from 1,500mm in rain-shadow valleys to over 3,000mm in exposed slopes. Cannabis vegetative growth peaks during this period.<ref name="Negi2012">Negi, V.S. et al. (2012). "Plant diversity and vegetation in relation to altitude in the high altitude cold desert of Lahaul-Spiti, Himachal Pradesh". ''Journal of Mountain Science''.</ref>
+== Cultivation History ==
-'''Autumn''' (October–November): Cooler temperatures (10–20°C) trigger flowering. Traditional harvest timing varies by valley and elevation, with communities timing collection based on resin maturity indicators.
+== Genetics ==
+No data at present, further research needed.
-'''Winter''' (December–March): Heavy snowfall above 2,500m, with temperatures dropping below freezing. Traditional seed selection and storage occurs during this period.
-'''Spring''' (April–May): Snowmelt and warming temperatures. Traditional planting season for most growing areas.
-==Traditional Cultivation History==
-===Ancient References===
-Cannabis cultivation in the Western Himalayas has documented history extending back at least to Vedic times, with references in ancient Sanskrit texts describing ''[[bhang]]'' and ''ganja'' use in religious and medicinal contexts.<ref name="Chopra1939">Chopra, R.N. & Chopra, I.C. (1939). "Indigenous Drugs of India". ''The Art Press''.</ref> Archaeological evidence and oral histories suggest continuous cultivation in specific valley systems for many centuries, though exact timelines remain subjects of ongoing research.
-===Colonial Period Documentation===
-British colonial administrators in the 19th century documented extensive cannabis cultivation throughout the Western Himalayas, with detailed reports from districts in Himachal Pradesh and Garhwal describing cultivation methods, local varieties, and trade networks.<ref name="Watt1889">Watt, G. (1889). ''A Dictionary of the Economic Products of India''. W.H. Allen & Co.</ref> These historical accounts provide valuable baseline data on pre-prohibition cultivation patterns.
-===Traditional Knowledge Systems===
-Local communities maintain sophisticated traditional knowledge regarding:
-* Optimal planting timing based on lunar cycles and snow conditions
-* Selection criteria for seed saving (resin content, maturity timing, plant structure)
-* Hand-rubbing techniques specific to individual valleys
-* Processing and storage methods for charas
-* Integration with mixed-crop agricultural systems

-* '''Eradication campaigns''': Government programs targeting cultivation areas
-* '''Habitat loss''': Development pressure in accessible valleys
-* '''Climate change''': Shifting precipitation patterns, changing snowpack timing
-* '''Knowledge erosion''': Loss of traditional cultivation knowledge as youth migrate
-'''Conservation Priority''': The Western Himalayas is considered '''vulnerable''' due to ongoing genetic contamination and enforcement pressures, despite continued cultivation in many areas. Urgent documentation and ''in situ'' conservation efforts are needed.
+=== Traditional Methods ===
-===Conservation Efforts===
+=== Modern Methods ===
-Current conservation activities include:
-* Field documentation of remaining landrace populations
-* Seed banking and ''ex situ'' preservation
-* Community-based conservation initiatives
-* Traditional knowledge documentation
-* Genetic characterization studies
-==Chemical Profile==
+== Conservation Status ==
-===Cannabinoid Content===
+=== Threats to Landrace Populations ===
-Western Himalayas populations are traditionally drug-type cannabis, selected for resin production. Preliminary chemotype studies indicate:
-* '''THC content''': Moderate to high (typically 8–18% in dried resin)
+=== Conservation Efforts ===
-* '''CBD content''': Low to moderate (often 0.5–3%)
-* '''Terpene profile''': Complex profiles varying by valley, commonly featuring myrcene, pinene, and caryophyllene
-Further research is needed to characterize valley-specific chemical profiles and their relationship to traditional quality assessments.
